1970 Quarter Error List with Pictures
A gold coin dated 1898 lies beneath the design of one extraordinary 1970-S quarter. That piece sold for $93,000 in January 2023.
Most 1970 quarter errors are far less exotic: thin blanks, extra letter outlines, or copper showing where a covering is missing. Estimated values here run from $5 to $125,000.
The S examples are Proofs, collector coins made with specially prepared tools and blanks. Follow the checks below to keep their unusual designs separate from ordinary Denver and no-mintmark quarters.
1. 1970 Washington Quarter Denver Rim Cuds
A raised blob that joins the rim can begin as a missing piece of the stamping tool. Metal enters that opening instead of receiving the normal portrait or lettering.
The result is called a cud. Two separate front-side cuds are cataloged for 1970-D quarters, each with its own shape.
The general error name does not locate the break on your coin. Its outline, its connection to the rim, and the nearby design are the useful clues, especially when distinguishing an original mint-made lump from a damaged edge or added material.
Estimated Value
Comparable genuine rim cuds have an estimated range of $5 to $200. A clear raised area that replaces part of the design generally attracts more attention than a tiny edge irregularity.
Surface condition remains important. A heavily worn or damaged rim can make even a real break difficult to recognize and display.
For the two Denver examples, compare the complete shapes rather than treating a shared year as proof of equal value. Larger does not automatically mean better preserved.
How to Identify
Locate where the raised area meets the original rim, then follow its boundary into the design. A cud should form part of the coin’s struck surface, not simply sit on top as a deposit.
Light the area from opposite sides to judge its height. Nearby letters may be partly lost where the tool no longer carried them.
Inspect the edge for a dent or fold that could have pushed metal upward after minting. Added solder can also mimic a blob, especially in a blurry photograph.
Compare the entire front with a documented Denver example, using neighboring letters as landmarks. Keep both cataloged shapes separate rather than assigning an unknown bump to either one by size alone.
2. 1970 Washington Quarter Repunched D and S Mintmarks
An extra outline around a mint letter can begin when its punch enters the stamping tool more than once. That is a repunched mintmark, rather than a second strike on the finished coin.
The documented Denver D has an earlier outline toward the left. San Francisco Proof reports include S shapes displaced toward the lower right and others entered at a slight tilt.
These are separate letter patterns, not several mintmarks expected on one coin. Each needs comparison with the correct mint and finish before a small extra curve can be assigned a name.
Estimated Value
An estimated $10 to $250 covers collectible repunched mintmarks across conditions and strengths. A complete, recognizable extra curve usually has more appeal than a faint fragment.
Circulation wear can erase the small details on a Denver coin. On an S Proof, haze or scratches can hide the letter despite the coin having no circulation wear.
The high end assumes a clear, correctly identified example with attractive surfaces. An unexplained bright edge around the letter does not support the same premium.
How to Identify
Identify the mint letter before choosing a comparison. The D example is an ordinary Denver quarter, while the S examples belong to Proof collector coins.
For the D, inspect the left side of the letter for the earlier outline. Use a close, sharply focused photograph to separate raised metal from reflections.
For an S, trace both curves and the little ends of the letter. Some reported patterns shift toward the lower right; tilted entries need their own matching shape.
Change the light direction and see whether the same extra parts remain. A flat shelf, contact mark, or moving highlight should not be used to complete an imaginary second letter.
Compare all surviving mintmark details, not just one enlarged corner.
3. 1970 Washington Quarter Denver Issue with a Proof-Style Back Design
The leaf beside the arrow tips can reveal a different back design on an ordinary Denver quarter. On the Type H design, a pointed leaf rises above the tips.
This design was associated with Proof coin production but also appears on certain ordinary Denver quarters, including 1970-D. Specialists classify the mismatch as use of the wrong design tool.
The wider spacing between E and S in STATES and the tail-feather pattern help identify the whole design. A pointed leaf by itself should not be treated as proof that every other feature matches.
Estimated Value
For a correctly identified 1970-D Type H back, estimate $10 to $300. Worn examples occupy the lower end, while clear detail and attractive unworn surfaces can increase interest.
The premium depends on the design match, not merely a shiny appearance. A normal S Proof already belongs to collector production and should not receive this Denver mismatch premium.
Photographs showing the leaf, STATES spacing, and tail feathers together give a buyer a better basis for comparison than one cropped leaf tip.
How to Identify
Find the D on the front first. The error discussed here pairs that ordinary Denver issue with the Proof-style back design.
On the back, locate the pointed leaf to the left of the arrow tips and compare its height with those tips. Then examine the space between E and S in STATES.
Check the tail feathers against a Type H reference photograph as a third design feature. These details should agree with one another rather than requiring a different variety to explain each part.
Wear can round a pointed leaf or soften feather lines, so avoid relying on one small shape. A shiny surface also proves little: polished circulation coins can look reflective without being Proofs or carrying the Type H design.
4. 1970 Washington Quarter Straight Clip with a Broadstrike
Two changes shape this Denver quarter: part of its blank is missing, and the remaining metal spread beyond its usual outline. NGC graded it MS65, meaning unworn with relatively few marks.
The straight clip originates in blank preparation. Broadstriking occurs later, when the collar ring fails to hold the metal within its normal width during the strike.
A plain expanded border is therefore different from the missing straight section. Both features belong to one coin, and the surviving design should explain their relationship without turning every uneven area into an additional separate error.
Estimated Value
A genuine straight-clip broadstrike has an estimated value of $25 to $500. A clearly missing section combined with an obvious original spread makes the accident easy to understand.
The recorded MS65 grade describes an unworn example with relatively few marks. Worn or damaged coins should be compared below similarly clear, better-preserved pieces.
The coin’s remaining date, the amount of spread, and the shape of the clip all matter. Value the complete object rather than adding full prices for each feature.
How to Identify
Start at the straight gap and trace its two ends into the round edge. Inspect the exposed thickness for cuts, filing, or other signs of later metal removal.
Now move away from the gap to the expanded border. The remaining design should flow into metal that spread beyond normal collar restraint, rather than appearing crushed by later hammering.
Use both-face photographs to see which details are absent because metal was missing and which remain within the wider outline. An unstruck patch still contains metal; the clipped section does not.
For a loose example, diameter and weight measurements can support those observations. Compare them with a normal 24.3-millimeter, 5.67-gram quarter, but let the original edge and design explain the shape.
5. 1970 Washington Quarter Reported Off-Center Strike
A blank sitting partly outside the stamping tools receives only part of the intended design. The untouched metal remains as a crescent beside the portrait and lettering.
Off-center strikes are reported for 1970, without one fixed mint, direction, or percentage defining the general type. The actual date and any surviving mint letter should remain visible in a useful comparison.
A coin with two separate impressions belongs to the repeated-strike group instead. The size of its displaced second strike cannot be used as the description of a simple single-strike example from the same year.
Estimated Value
Estimate $40 to $500 for a genuine single off-center example, depending on displacement and condition. A complete year usually makes the error more appealing than an incomplete date.
As a nearby-year comparison, a 1974 quarter struck 45% off center sold for $94 in January 2022. That result concerns a single displaced strike, rather than a double strike.
A large untouched crescent can be dramatic, but heavy scratches or later flattening can substantially reduce the coin’s appeal.
How to Identify
Keep the complete outline in view when photographing the coin. Locate the date within the surviving design before describing its year or mint.
Compare the front and back boundaries between plain metal and struck detail. They should fit one blank misplaced relative to both stamping tools.
If the back is centered normally, examine the possibility that only the front tool was shifted. If two portraits or distinct groups of letters survive, investigate another strike instead.
Check the plain crescent for signs that an existing design was ground away. It should not show leftover letters or scraping that explains its blank appearance.
An edge view also helps separate a solid untouched area from an actual missing piece of the blank.
6. 1970 Washington Quarter Dime-Thickness Stock and an Indented Example
A quarter made from dime-thickness strip can keep a normal quarter diameter while weighing about 4.2 grams. The metal strip was intended to be thinner than quarter stock.
Quarter-sized disks cut from that strip then received the Washington design. The result differs from a quarter struck on a complete, small dime blank.
One Denver example combines the thin stock with a front depression caused during striking. It weighs 4.21 grams and is graded NGC MS64; the hollow is an additional feature on that particular coin, not a requirement for all thin-stock quarters.
Estimated Value
Ordinary dime-stock examples have an estimated range of $20 to $350. Allow about $150 to $750 for a well-preserved combination with a clear original indent.
Historical Numismatic News guidance placed circulated pieces around $7.50 to $10 and unworn pieces around $20 to $25. Those older figures show that the thin-stock type need not be a spectacular rarity.
Clear identification, remaining design, surface quality, and the extra depression determine where a present-day comparison fits within the estimates.
How to Identify
Measure a loose candidate before interpreting weak lettering. A normal quarter is about 24.3 millimeters across and weighs 5.67 grams; dime-stock examples retain roughly that diameter at around 4.2 grams.
Inspect both outer layers and the copper center along the thin edge. A missing outer layer changes that structure, while acid or grinding can remove metal after minting.
Check the surfaces for pitting and scrape marks. Original weak detail may reflect the thin blank, but damage should not be mistaken for a mint-made shortage of thickness.
For the 4.21-gram indented example, also examine the bounded hollow on the front. The depression remains a separate visible feature within the same thin-stock coin.
7. 1970 Washington Quarter Missing Outer Clad Layer
Copper showing through one face can reveal an absent outer layer. A normal quarter sandwiches a copper center between two pale copper-nickel coverings.
A Denver example graded NGC MS66 lacks the back covering and weighs 4.6 grams. Another recorded Denver coin, graded ANACS AU58, has a missing layer without its affected face specified in the title.
The weight and face of one example should not be assumed for the other. The coin’s edge and original struck surface matter more than brown color, because stains and later treatments can imitate exposed copper.
Estimated Value
The AU58 example brought $104 in December 2011. The separate MS66 back-layer coin sold for $192 in June 2023.
For comparable authenticated examples, estimate $75 to $750. The clarity of the exposed surface and its remaining detail help explain differences between individual sales.
A bright, attractive copper face can display better than a dull damaged one. Neither a higher grade nor stronger color alone guarantees a larger premium for the missing covering.
How to Identify
Put photographs of both faces beside an edge view. The copper-colored face should connect to a missing pale layer in the edge structure.
Look closely at letters and open areas on that face for original struck detail. Later grinding leaves abrasion, while chemical removal can leave an etched or rough texture.
If the coin is loose, weigh it without cleaning it first. The 4.6-gram back-layer example provides a useful comparison with a normal 5.67-gram quarter.
Do not use that figure as a universal pass-or-fail limit. A candidate’s surface, layers, and weight need to support the same explanation, and a grading holder should remain closed during the examination.
8. 1970 Washington Quarter Struck on a Nickel Blank
The Washington design is too large for a nickel blank, so some outer details can run off the available metal. The resulting coin is smaller and lighter than a normal quarter.
Nickel blanks contain the same copper-nickel alloy throughout, without the copper-center sandwich used for quarters. Their ordinary starting weight is about five grams.
A recorded 1970-D example was graded PCGS AU58. Another ANACS AU50 example weighs 4.99 grams, providing a separate measured coin; its weight should not be assigned to the first example simply because both used nickel blanks.
Estimated Value
The PCGS AU58 example sold for $172.50 in August 2009. Allow an estimated $150 to $1,200 for comparable genuine nickel-blank quarters.
The visible date and D make a useful difference when the smaller blank cuts off surrounding details. Better-preserved surfaces can also improve the display.
Both recorded AU grades describe circulation wear, so a clean unworn piece needs a different condition comparison. A damaged smaller quarter should not receive this premium without a sound identification of its blank.
How to Identify
The edge can separate this error from an ordinary clad quarter. Look for metal of one basic alloy through its thickness rather than pale coverings around a copper-colored center.
Next follow the outer design to see where it ends at the smaller blank. Read the surviving D and date directly, keeping them visible in the full-coin photograph.
A loose candidate can be weighed and measured: a standard nickel blank begins around five grams and 21.2 millimeters. Striking may change its final width.
Search between the quarter features for any earlier Jefferson portrait or nickel lettering. Those remnants would indicate a finished nickel overstruck as a quarter, rather than the unused blank described here.
9. 1970 Washington Quarter Struck on a Cent Blank
A copper-colored quarter can begin as a cent blank mistakenly fed into the larger coin’s press. Its Washington design may be incomplete because the small blank does not reach every part of the tool.
A 1970-D example is cataloged as PCGS MS65 Brown. That means an unworn coin with relatively few marks and predominantly brown copper surfaces.
The cent blank used for this period was copper-based, unlike the much lighter copper-plated zinc cents common today. Brown color fits the metal, but it cannot establish the error without the right size, weight, and struck design.
Estimated Value
For an authenticated cent-blank quarter, estimate $500 to $2,500. A clean coin with an intact year and mintmark is easier to collect than one with its identity mostly off the edge.
For comparison, a 1974-D MS64 cent-blank quarter sold for $977.50 in January 2010. A no-mintmark 1974 MS62 example brought $540 in December 2024.
These are different-year comparisons, not sales of the recorded 1970-D MS65 coin. Its own surfaces and remaining design should guide the final value.
How to Identify
Begin by confirming that the visible portrait and letters belong to a quarter. A brown disk with a vague profile is not enough to identify the wrong denomination’s design.
For a loose candidate, compare the measurements with a normal period cent blank: 3.11 grams and about 19.05 millimeters before striking. Some spreading is possible under the larger quarter tools.
Inspect the edge for a copper-based structure rather than the quarter’s layered metal. Added copper on a normal quarter changes color without explaining a genuinely smaller cent-sized blank.
Look around the date and D for undisturbed struck detail. Scraping or clipping a normal coin down to a smaller outline damages the edge and does not reproduce this original fit of design to blank.
10. 1970 Washington Quarter Reported Strike on a Small Dime Blank
A true dime blank is smaller in diameter than a quarter blank, not merely thinner. A quarter design struck on it loses substantial outer detail.
Mint Error News reported a 1970-D quarter on a dime blank with the date and mintmark area intact. The listing described a coin graded PCI AU58.
That surviving identity makes the small piece particularly useful to collectors. It must not be confused with the quarter-sized dime-stock errors, which weigh around 4.2 grams and retain a much wider outline despite their reduced thickness and often weak outer details.
Estimated Value
A dime-blank example has an estimated range of $500 to $3,000. Keeping the year and D readable can improve appeal when much of the larger design falls outside the small blank.
As a different-year comparison, a 1987 quarter on a dime blank brought $253 in a September 2010 auction-results report. The date on that example was incomplete.
The 1970 example needs its own comparison for visible identity, condition, and authentication. The range is an estimate, not its recorded selling price.
How to Identify
Compare the full outline with both an ordinary dime and an ordinary quarter at the same image scale. This error should be dime-sized, unlike a quarter cut from thinner dime strip.
If the coin is loose, measure it and record its weight. A standard clad dime blank starts around 17.91 millimeters and 2.268 grams before any spreading during the strike.
Check that the date and D are genuinely visible rather than supplied by a label alone. Follow nearby quarter details to the edge where the small blank could not hold the rest of the design.
Inspect for trimming, filing, or joined pieces. A specialist should confirm the blank and original strike before a small altered coin is priced as the reported error.
11. 1970 Washington Quarter Struck on a Philippine Twenty-Five-Cent Blank
A foreign blank can carry Washington’s portrait without ever having carried a foreign design. The recorded 1970-D example used an unused Philippine twenty-five-cent blank.
NGC graded the coin MS65 and recorded its weight as 4.1 grams. That measurement belongs to this particular wrong-blank specimen, rather than a normal United States quarter.
Its blank was intended for another country’s coinage before receiving the Denver quarter design. The separate 1970-S Proof over a finished Philippine coin has older lettering beneath the new design, so it tells a different sequence of events.
Estimated Value
The 4.1-gram MS65 example sold for $930 in June 2023. An estimated range of $500 to $3,000 covers comparable authenticated foreign-blank quarters.
A recognizable Washington design and readable D help establish the United States strike. The blank’s material and dimensions must also support its Philippine identification.
Clean surfaces and a clear design improve its appeal, while scratches or an incomplete date can reduce it. A low weight alone does not make a quarter this particular foreign-blank error.
How to Identify
Around 4.1 grams is close to the weight of some dime-stock quarters, so the scale cannot make the identification alone. Compare the edge structure, diameter, and material as well.
Check that the D and surviving year belong to the actual coin. Keep both faces in view so the Washington design can be followed around the smaller available surface.
Look for an older Philippine design beneath it. Its presence would change the identification from an unused blank to a finished foreign coin struck again.
An expert can assess whether the metal and dimensions match the Philippine blank. Use the authenticated 4.1-gram example as the complete comparison, rather than combining its weight with another coin’s photographs or mintmark.
12. 1970 Washington Quarter Doubled Dies and Shared Design Doubling
Two outlines in a letter can originate on the die, the steel tool that stamps coins. Coins struck from that doubled die repeat the same extra detail.
On 1970 quarters, recognized examples occur with D, with no mintmark, and on S Proofs. The affected areas differ: front lettering and dates on some, eagle-side lettering and leaves on others.
Some back-side doubling came from an earlier master tool shared by many working dies. That widespread feature is not automatically a rare variety; the whole pattern needs comparison with a known example from the correct mint.
Estimated Value
Minor identified doubled dies have estimated values around $10 to $300. Strong Denver varieties can reach an estimated $100 to $3,500, while minor S Proof examples are estimated at $20 to $500.
A Denver FS-102 coin graded MS65 sold for $2,875 in January 2012. A separate AU58 example brought $303.75 in August 2018.
Those prices concern that variety and condition. Widespread master-tool doubling alone does not earn the same premium over an ordinary coin.
How to Identify
Separate the coin by mint and finish before selecting a picture. A D on an ordinary quarter and an S on a Proof do not share one interchangeable doubling pattern.
On Denver fronts, inspect LIBERTY, the motto, date, and hair ribbon for matching extra outlines. No-mintmark examples also include thickened motto letters with notches at their upper-left corners.
For a back-side candidate, compare letters, wing details, and leaves together. Some common doubling below the eagle came from shared master tools, so a doubled denomination alone is insufficient.
S Proof comparisons include LIBERTY on the front and UNITED or the denomination on the back. Match the actual visible detail rather than trusting a similar catalog number from another mint.
A flat shelf beside a letter is not the same as a separate rounded outline.
13. 1970 Washington Quarter Repeated Strikes with Shifted Designs
Proof coins normally receive repeated blows, but those blows should reproduce the same aligned image. A tool turning between them can leave two different positions of the front design.
One 1970-S PR67 Cameo example has counterclockwise front doubling and a normal back. Another PR66 Cameo example turned about 20 degrees clockwise and also shows clash marks from the tools touching without a blank.
A Denver coin instead received a second strike 70% off center. Its displaced impression reflects movement of the coin, unlike the shifted Proof tool acting within the restraining collar ring.
Estimated Value
Ordinary repeated strikes have an estimated range of $150 to $2,000. For the unusual S Proof combinations, allow roughly $750 to $5,000, depending on clarity and preservation.
The PR66 Cameo coin with rotated front impressions and clash marks sold for $1,989.50 in August 2007. Cameo describes frosted designs against reflective open areas, not another error.
The relationship between the impressions matters more than the number of visible shadows. Damage to reflective Proof surfaces can reduce the price considerably.
How to Identify
On an S Proof, distinguish ordinary repeated striking from visible displacement. Compare the date and lettering for two clearly different positions, then check whether the back stayed aligned.
The PR66 example also has an E above the 1 and 7 in the date and traces of the portrait within the wing on the viewer’s left. Those clash marks came from contact between the tools, not a third strike on the coin.
For the Denver example, follow the separate impression near the edge and its overlap with the earlier design. Its 70% figure describes that second strike, not the first.
Keep the direction and added features with each photographed specimen. A clockwise Proof pattern should not be matched by borrowing the counterclockwise movement of the other example.
14. 1970 Washington Quarter Proof Over a Finished Philippine Coin
Older Philippine lettering can remain beneath Washington when a finished foreign coin is struck again in a quarter press. It is an overstrike, rather than a strike on an unused foreign blank.
The recorded 1970-S Proof example is graded NGC PR64. Remnants of the Philippine coin appear on both sides, including upside-down back lettering beneath the quarter’s front design.
Dealer Mike Byers described this as an intentionally made piece. That is the dealer’s account of its origin; the visible older design establishes the finished host coin without requiring a story about how it entered the press.
Estimated Value
Estimate $3,000 to $15,000 for this kind of authenticated Proof overstrike on a finished Philippine coin. The visible host details and the condition of the Proof surface influence its appeal.
For a related foreign-coin comparison, a 1970-S Proof over a George V Canadian quarter sold for $7,800 in August 2020. The host country and design differ.
The dealer’s sold label on the Philippine example does not disclose a realized amount. This range is therefore an estimate, not that transaction’s price.
How to Identify
Rotate a photograph of the front to follow the upside-down Philippine lettering. Look for several connected features rather than trying to identify a country from one stray line.
On the back, search for additional remnants of the older coin beneath the Washington design. Their relationship should support a finished host that received another complete design.
Compare the overlaps under light from different directions. Later engraving, joined pieces, or a novelty counterstamp will not reproduce the same original layers of struck detail.
Keep the coin in any existing grading holder while examining it. Match the PR64 example’s surviving host features, rather than substituting the 4.1-gram Denver Philippine-blank coin, which had no earlier design to leave behind.
15. 1970 Washington Quarter Proof Over a Barber Quarter
The word DOLLAR belongs on a quarter’s back, but it appears near the S mintmark on this coin’s front. It survived from a Barber quarter used as the host.
The older silver quarter received a new 1970-S Proof design. NGC graded the resulting overstrike PR65, with remnants of the Barber back visible beneath Washington’s front.
The older coin’s date has not been established. Its design identifies the host series, while the surviving overlap tells the sequence; neither detail permits an exact Barber year to be supplied where no year can be read.
Estimated Value
For an authenticated Barber-quarter Proof overstrike, estimate $5,000 to $20,000. This coin did not sell in its August 2011 Heritage offering.
A related 1970-S Proof over a George V Canadian quarter brought $7,800 in August 2020. That different silver host offers a comparison, rather than a sale result for the Barber piece.
The legibility of the older design and the preservation of the newer Proof surface are major price factors. A clear overlap helps collectors understand the unusual combination.
How to Identify
Find the S and inspect the nearby surface for the older word DOLLAR. Change the lighting angle gently; faint host details can disappear under glare from the Proof surface.
Trace those letters into other surviving Barber-back features beneath the portrait and open areas. Several matching parts establish more than one word on its own.
The auction description reports no visible host design on the Washington back. Do not reject a match merely because both faces fail to show equally strong older detail.
Compare the metal and surviving designs with the authenticated example, keeping any holder closed. An added inscription or silver-colored coating cannot reproduce the complete overstrike, and an unreadable host date should remain unreadable rather than guessed.
16. 1970 Washington Quarter Proof Over Canadian Quarters
A second date beneath the eagle can belong to a much older Canadian coin. On one 1970-S Proof overstrike, the flattened 1941 remains readable near DOLLAR.
That George VI host example weighs 5.63 grams and was graded NGC PR65. A different 5.3-gram PR64 coin used a George V quarter whose exact year is not established.
On the George V piece, maple leaves survive near the front’s outer area, while older lettering and the king’s shoulder appear on the back. These are two host coins, not alternate descriptions of the same example.
Estimated Value
The George V overstrike sold for $7,800 in August 2020. Comparable authenticated Canadian-quarter Proof overstrikes have an estimated range of $7,500 to $40,000.
The 1941 piece did not sell in its August 2011 Heritage offering. A later $35,000 dealer asking price was widely reported, but it was not a confirmed auction result.
Host identity, surviving detail, and condition explain why one record cannot simply be assigned to the other. Both are collectible complete coins, not ordinary quarters with unusual dates.
How to Identify
Choose the right host comparison before searching for a date. The 1941 example has its older date near DOLLAR on the Washington back, while the George V host has no established year.
For the George V coin, inspect the front perimeter for maple-leaf remnants. On the back, look near nine o’clock for REX ET and near AMER for part of the king’s shoulder.
Follow several remnants into a consistent older Canadian design beneath the quarter design. A scratched-in date or isolated letter cannot establish an overstrike.
Keep the recorded weights separate: 5.63 grams belongs to the 1941 example, and 5.3 grams to the George V piece. Neither figure is a universal test for every coin with Canadian-looking marks.
17. 1970 Washington Quarter Proof Over an 1898 Five-Dollar Gold Coin
This gold-colored quarter contains an older gold coin beneath its Washington design. A finished 1898 five-dollar piece received the 1970-S Proof impressions.
The host is called a half eagle, the traditional name for a United States five-dollar gold coin. Its older date survives beneath the wreath on the quarter’s back.
NGC graded the overstrike PR66 and recorded a weight of 8.3 grams. The small gold host could not fully fill the larger quarter design, leaving incomplete outer detail; it was not a regular gold quarter issue released alongside ordinary 1970 coins.
Estimated Value
The 1898 gold-coin overstrike sold for $93,000 in January 2023. A working estimate for this exceptional authenticated piece is $75,000 to $125,000.
That valuation depends on its documented identity and original overlapping designs, not simply the gold content or the 1970 date. A gold-plated ordinary quarter belongs to a completely different market.
Proof surface quality and the visibility of the older coin affect collector appeal. The actual auction result remains the strongest specific price reference here.
How to Identify
Start with the older 1898 date below the wreath, using strong magnification and light from a low angle. The host details are faint, so a bright gold surface alone proves little.
Trace other surviving parts of the five-dollar design beneath Washington’s impressions. Their connected arrangement must fit one earlier coin, rather than unrelated marks on a plated quarter.
The recorded weight is 8.3 grams, much heavier than a normal 5.67-gram clad quarter. Keep the certified example sealed rather than removing it merely to repeat a measurement.
Compare the outer design’s incomplete definition with the authenticated photographs. Expert examination of the metal, surfaces, and overlapping designs is essential before a gold-colored candidate can be compared with this exceptional piece.
Conclusion
A thin 1970-D quarter and a gold 1970-S overstrike belong at very different ends of the estimated $5 to $125,000 range. Start with the coin’s mint, finish, and visible physical change.
For small varieties, compare the actual letters and leaf shapes. For an overstrike, identify the older design beneath Washington; color alone cannot turn a plated quarter into a rare gold or silver error.
