1971 Nickel Error List with Pictures

An empty space below the date means little on an ordinary 1971 Philadelphia nickel. On a genuine San Francisco Proof made for collectors, however, a missing S can matter greatly: one brought $7,637.50 in 2016.

This 1971 nickel error list covers estimated values of $5–$10,000, from small surface flaws to that scarce missing-mintmark issue. Read the examples below to separate the coin’s finish, metal, and visible mistake.

1. 1971 Jefferson Nickel A Reported Missing Edge Section

A curved or straight section missing from the edge may have begun before the coin was struck. An incomplete metal disk entered the press and received the design only on the metal that remained.

This is a clipped blank. Later cutting or filing can produce a similar outline without being a Mint error.

The proposed 1971 example has a conflicting date description, so it does not yet establish a confirmed specimen for this year. The actual date must be read before applying a year-specific identification.

The missing section’s original boundary is equally important.

Estimated Value

If a genuine 1971 clip is confirmed, estimate $15–$75 for a modest worn example and $75–$200 for a stronger, attractive piece. These estimates do not authenticate the unresolved listing.

A 1997-P nickel with a twenty-percent clip brought $124 in March 2025, offering a different-year comparison. The amount of missing metal, readable date, and original striking effects matter more than a seller’s error label by itself.

How to Identify

Read the complete date first and photograph it beside the missing edge section. The conflicting listing cannot establish 1971 for a coin whose digits are unclear.

Use a 10× magnifier to inspect both ends of the gap for sawing, filing, or cuts through finished details. Check the remaining plain edge and the border opposite the opening for supporting signs of an incomplete blank.

A scale reading below the normal 5 grams only shows reduced metal, since later cutting also lowers weight. Compare intact spans with 21.2 millimeters using calipers and have the original boundary examined before accepting the clip identification.

 

2. 1971 Jefferson Nickel A Repeated D or S Mintmark

A small extra curve can follow part of the D or S. Workers added these mintmarks to individual steel stamping tools with a punch, and a shifted second punch could leave both impressions.

Coins then repeated those overlapping shapes. This is a repunched mintmark, rather than a whole letter being placed too high or low.

Catalogs record both Denver circulation coins and San Francisco Proofs for 1971. Proof means a specially made collector coin, usually with mirrored flat surfaces.

The direction of the extra impression varies, so one example cannot supply the position for every mintmark.

Estimated Value

Estimate $10–$75 for minor authenticated examples and $75–$250 for clear, attractive pieces. These are type estimates rather than quoted sales for particular 1971 catalog numbers.

A well-preserved Proof can also have value for its finish, separate from the repeated S. The extra letter shape should be identifiable in its own right; a filled mintmark or flat strike doubling does not automatically qualify for a repunched-mintmark premium.

How to Identify

Choose the correct comparison before examining tiny lines: a D belongs to Denver, while an S belongs to a San Francisco Proof. An ordinary Philadelphia nickel has neither letter.

With a 10× magnifier, follow the extra curve around the main mintmark. Cataloged examples differ in direction, so compare the entire shape with one matching listing.

Move the lamp to separate shadows from metal. A shelf flattened beside the letter is different from a second punched outline.

On a loose coin, use a scale and calipers to check about 5 grams and 21.2 millimeters. Inspect the plain edge and the mintmark’s base for damage or added metal before assigning a variety number.

 

3. 1971 Jefferson Nickel Design Blocked by Material during Striking

A depression or a softly missing detail can form when material lies between the coin and its stamping tool. The obstruction keeps the normal design from reaching that area.

This is called a struck-through error. A 1971 year guide reports the category without establishing a particular material or position for every example.

Soft material can leave weak details, while a firmer object may leave a more defined impression. The shape must support the proposed cause before a specific material is named.

A dent made after striking can look similar but disturbs an already finished surface.

Estimated Value

For confirmed struck-through errors, estimate $5–$50 for small weak areas and $50–$300 for clear, substantial impressions on attractive coins. These are estimates for the reported category, not a sale assigned to an unidentified 1971 specimen.

A distinct original impression generally offers more collector interest than a single faint letter. Later dents, scratches, and heavy wear should not be priced from the same range merely because some design is missing.

How to Identify

Look at the surrounding design before naming the object that supposedly blocked it. A clear depression can be original even when its material cannot be identified.

Check a loose coin on a scale against 5 grams and use calipers against the normal 21.2 millimeters. Inspect the plain edge for a blow that may explain a nearby dent.

Under a 10× magnifier, compare the affected surface with the adjacent undamaged area. Raised displaced metal or a scrape across finished details can indicate later contact.

Do not clean the mark or fit an object into it. Photograph the whole face so a specialist can judge how the interruption relates to the struck design.

 

4. 1971 Jefferson Nickel A Doubled Design in the Stamping Tool

Split corners and rounded extra edges can come from the stamping tool rather than a second blow to the coin. A tool carrying duplicated design is called a doubled die.

Philadelphia front doubling is cataloged for 1971. San Francisco Proof listings include both front and back doubling, which need their own comparisons.

The cataloged patterns differ in strength and spacing. A photograph of one letter on a Proof should not be used to identify an ordinary Philadelphia coin.

Flat steps caused by movement during striking can imitate doubled edges without being the same kind of variety.

Estimated Value

Estimate $20–$100 for modest identified varieties and $100–$400 for strong, attractive examples. The range includes the coin’s condition and finish as well as the repeated design.

These are estimates, not interchangeable prices for all Philadelphia and San Francisco listings. A Proof with a doubled back is separate from the No S issue, and the valuable missing-mintmark price should not be borrowed for a coin simply showing doubled lettering.

How to Identify

Write down whether the coin has an S before comparing doubled lettering. Its presence identifies a Proof comparison, while Philadelphia circulation pieces normally lack a mintmark.

Use a 10× magnifier to examine several corners and curves on the affected face. A consistent pattern across more than one detail is more useful than a single thick letter.

Compare a loose coin with 5 grams and 21.2 millimeters using a scale and calipers, and inspect the plain edge for squeezing.

Move the light slowly to test whether the extra shape remains visible. Flat ledges need a different explanation from rounded repeated design.

Keep the other face in your photographs, even when only one side shows doubling, so the full coin can be matched correctly.

 

5. 1971 Jefferson Nickel Changed Surface Color with a Low D

The surface can become unusually dark or coppery before the design is struck. Wrong conditions during annealing, the heating step used to prepare blanks, can change its appearance.

Several 1971-D examples were graded PCGS MS65 with improper-annealing and low-mintmark descriptions. The color and the D’s position are two visible features on those coins.

A low D does not explain the color. Nor does brown color prove that a coin was struck on a penny blank.

Ordinary nickel metal is a uniform copper-nickel alloy, without a separate outer layer that can simply go missing.

Estimated Value

One PCGS MS65 example with a low D and improper annealing sold for $149 in July 2022. Estimate $40–$150 for authenticated worn or marked pieces and $150–$400 for attractive unworn examples.

That price covers the complete coin with both features. A dark nickel altered by later heating or chemicals does not receive the same estimate, and normal small differences in mintmark position do not establish this specific combination.

How to Identify

Compare the coin’s shape and measurements before treating its color as proof of a wrong blank. A loose full-size nickel should be close to 5 grams on a scale and 21.2 millimeters on calipers.

Examine the plain edge and both surfaces with a 10× magnifier. Added plating, blistering, and obvious burning call for further examination rather than an automatic Mint-error label.

Then compare the D’s position with the certified low-mintmark example using the date as a fixed reference. Keep that position check separate from the color assessment.

Leave the surface untouched for a specialist. Cleaning can remove evidence needed to distinguish pre-strike heating from chemical or heat treatment after the coin was made.

 

6. 1971 Jefferson Nickel A Wide Separation on the Back Surface

A strip or patch of surface metal can lift or break away from a nickel. A weakness inside the blank allows the metal to separate, producing a lamination.

One 1971 example was auctioned with a broad lamination on the back. The description does not establish a particular mintmark or clock position for the separation.

The separated area belongs to the nickel’s own metal. It is different from a depression left by material caught between the blank and a stamping tool.

Nickel metal has no separate outer coating whose absence would automatically explain a peeled area.

Estimated Value

For an authenticated back lamination, estimate $15–$100 on worn coins and $100–$450 for wide, attractive examples. A well-defined separation with the date intact is easier to appreciate than rough general corrosion.

The recorded 1971 coin was part of a six-coin sale, so its individual result cannot be extracted by assigning the lot total. These are condition-based estimates for the lamination, and removing an attached flap can reduce its value.

How to Identify

Protect any raised flap before turning the coin over. Never pick at it to see how far the separation extends.

Look along the boundary with a 10× magnifier and low side lighting. A lifted layer or shallow peeled area should be distinguished from a scratch cut across finished design.

If the coin is safe to handle, a scale can compare its weight with the normal 5 grams. Calipers should be used on intact spans against 21.2 millimeters.

Examine the plain edge where relevant, then photograph the nearby original surface. Corrosion can roughen metal without producing the same separation.

Keep the whole back in view so the layer’s shape and relationship to Monticello remain visible.

 

7. 1971 Jefferson Nickel A Crack through the Original Blank

An opening can extend into the nickel itself instead of sitting as a raised line on its surface. The metal blank was cracked when it received the design.

Heritage listed a Philadelphia example graded NGC AU58, meaning very light wear. Its crack belongs to the coin’s metal, not to a broken stamping tool.

That difference matters: a tool crack usually leaves a raised trace, while a cracked blank has an actual separation. A cut or a bend made after minting can also open the metal.

The boundary and surrounding design must establish which explanation fits.

Estimated Value

The NGC AU58 cracked-blank 1971 nickel sold for $46 in October 2022. Estimate $25–$125 for worn genuine examples and $125–$500 for stronger pieces with clear original separation.

The low auction result shows that a visible crack need not make a coin expensive. Size, appearance, and stability all affect interest, while a break caused by later bending should not receive a Mint-error premium.

How to Identify

First determine whether the line is an opening or raised metal. Side lighting through a 10× magnifier helps separate a crack in the blank from the raised trace of a cracked stamping tool.

Follow the opening toward the plain edge without flexing the coin, looking for later cutting marks or a bend. A scale may still read near 5 grams when the two sides remain attached and little metal is missing.

Use calipers gently across intact spans against the normal 21.2 millimeters, rather than squeezing across the crack. Preserve photographs of both faces and the edge so the design near the separation can be assessed together.

 

8. 1971 Jefferson Nickel A Raised Patch Joined to the Rim

A swollen patch beside the border can replace normal lettering or design. A piece broke from the edge of the steel stamping tool, leaving a space that coin metal could fill.

The resulting raised patch is called a cud. Specialist catalogs list two 1971-D examples, with their different shapes kept as separate comparisons.

The patch should belong to the struck metal and connect to the rim. An attached blob or a dent that pushes the edge inward can imitate the appearance.

Its exact outline matters more than merely finding a thick-looking section of the border.

Estimated Value

Estimate $20–$150 for worn 1971-D cuds and $150–$600 for stronger examples on attractive coins. These are estimates for the type rather than prices attached to each catalog number.

A lightly worn 1983-P cud sold for $63 in July 2022, offering a different-year comparison. Larger visible breaks can attract more interest, but an ordinary rim dent is damage and should not be valued as missing metal from the stamping tool.

How to Identify

Inspect the plain edge next to the lump before studying its outline. A dent or folded rim can push existing metal into the face and create a false cud.

Use a scale and calipers on a loose candidate to compare it with about 5 grams and 21.2 millimeters. Added material may affect those measurements, though normal readings do not authenticate the patch.

Under a 10× magnifier, trace the raised area where it joins the rim and replaces the usual design. Look for an attachment seam or a different surface texture.

Turn the coin over to check the opposite area, which may show weak detail. Match the complete patch with a documented 1971-D example instead of choosing a number from size alone.

 

9. 1971 Jefferson Nickel A Shifted Strike on an Ordinary Nickel Blank

The design can land to one side and leave part of the metal untouched. This happens when a blank misses its normal position between the stamping tools.

The result is an off-center strike. Both faces should reflect the same misplaced disk, rather than only one face having an uneven border.

A 1971 year guide reports ordinary off-center nickels without establishing a specific mint or percentage for every example. Those reports are separate from the certified coin struck on a smaller dime blank.

A clear date is necessary before an undated partial design can be assigned to this year.

Estimated Value

For confirmed 1971 off-center nickels on normal blanks, estimate $25–$150 for modest displacement and $150–$750 for dramatic, attractive examples with readable dates. These are estimates rather than prices for an unidentified guide illustration.

A 1999-D sixty-five-percent off-center nickel sold for $75 in September 2024. That different-year comparison shows why the percentage alone does not set value; surface quality and the surviving date remain important.

How to Identify

Keep the whole outline in view while reading the date, so a blank crescent is not mistaken for missing metal. An ordinary off-center nickel still has metal in that unused area.

Compare both faces at the same orientation and use a 10× magnifier along the boundary where design ends. Grinding away letters leaves an altered surface rather than original unstruck metal.

A scale should put an undamaged loose example near 5 grams, while calipers can compare intact spans with 21.2 millimeters. Inspect the plain edge for trimming, and have a much smaller or lighter candidate assessed for a wrong blank rather than assuming ordinary displacement.

 

10. 1971 Jefferson Nickel A Reported Nickel on Dime-Thickness Metal

A nickel-sized disk can be cut from metal intended for another coin. That differs from a small completed dime blank entering the nickel press.

Error researcher Mike Diamond described a 1971-D nickel that apparently came from layered dime stock. The word apparently matters: the proposed origin was an interpretation, not an unqualified identification.

The same coin had significant heat and physical damage. Those later-looking changes cannot automatically be counted as mistakes made inside the Mint.

Its metal, size, and surviving original surfaces need to support the wrong-stock explanation despite the damage.

Estimated Value

If the dime-stock origin is authenticated, estimate $100–$500 for a heavily affected example and $500–$1,500 for a clearer, attractive specimen of the type. These are conditional estimates, not a quoted sale of Diamond’s coin.

A 1987-P nickel on quarter stock sold for $1,175 in October 2012, providing a different-year and different-metal comparison. Heat damage does not create an additional premium, and it can make the original blank harder to identify.

How to Identify

Begin with the metal question, not the damage. A normal nickel is one copper-nickel alloy, while dime stock consists of bonded layers with copper in the center.

Use a 10× magnifier to inspect any exposed boundary at the plain edge without scraping or cutting. Heat can change the surface, so color alone cannot establish the original layers.

Record the loose coin’s weight on a scale and width with calipers against the normal 5 grams and 21.2 millimeters. These standards are not reported measurements for the damaged specimen.

Photograph surviving sharp design and damaged areas separately. A specialist may need metal analysis to assess the proposed stock origin; a thin or burned nickel alone is not enough.

 

11. 1971 Jefferson Nickel Repeated Strikes and Contact with Other Blanks

Additional impressions can overlap a nickel that fails to leave the press. One Denver triple strike began normally, then received two blows near the edge.

A new blank blocked its back during the final blow. A separate Denver double strike has its second impression thirty-five percent off center.

Another collector-reported coin flipped over before a weak second strike. Its front also shows a plain depression from a blank and backward detail pressed by another struck nickel.

That backward, sunken detail is called brockage. The plain depression and the mirror image should not be confused with each other.

Estimated Value

The PCGS MS64 1971-D triple strike sold for $97.75 in February 2005. Estimate $100–$500 for modest repeated strikes and $500–$2,000 for attractive, complex combinations.

That older sale concerns a specific coin with a small later scratch, not every three-strike example. Clear overlapping designs can matter more than the number of blows, while the collector-reported flip-over combination needs its own assessment of the blank impression and backward image.

How to Identify

For the triple strike, locate the full first impression before tracing the two small later ones. With that first design upright, the catalog places them near nine and twelve-thirty.

Use a 10× magnifier to follow where a later impression crosses earlier details. The final strike’s blocked back does not mean the whole coin has only one designed face.

A scale and calipers can record a loose nickel against 5 grams and 21.2 millimeters. Inspect the plain edge for later squeezing.

On the separate flip-over coin, distinguish a plain depression from a sunken backward design. A faint raised ghost alone does not establish brockage.

Keep the U-shaped scratch above Monticello’s dome on the triple strike separate from its original overlapping impressions.

 

12. 1971 Jefferson Nickel A Cup-Shaped Nickel on a Dime Blank

A thin, small disk can become cupped after sticking to the front stamping tool. It stays with the tool while repeated operation stretches and reshapes the metal.

The resulting coin is called a die cap. A recorded 1971-D example formed on a dime blank and was graded NGC MS64.

Its listed weight is 2.6 grams. That is the recorded measurement for this cap, not the 2.3 grams reported for a separate double-struck dime-blank nickel.

The cup shape and the wrong blank belong to one coin. Later bending can imitate cupping without producing the same stretched design.

Estimated Value

The NGC MS64 dime-blank cap brought $881.25 in August 2016. Estimate $500–$1,200 for less attractive genuine examples and $1,200–$2,500 for strong, well-preserved pieces.

The estimate covers the whole compound error, rather than adding a cap price to a wrong-blank price. Damage from flattening the cup can reduce both its appearance and the evidence showing how it formed.

Its fragile walls deserve careful handling.

How to Identify

Support the cup gently and photograph its side profile before taking measurements. Do not press it flat to compare it with a normal nickel.

A scale can check a safely handled loose example against the reported 2.6 grams, while a normal nickel weighs 5 grams. Calipers can record width and height rather than forcing its altered outline to match the usual 21.2 millimeters.

Under a 10× magnifier, examine the portrait-side base and the stretched wall for natural design changes. Inspect the plain edge for plier marks or a sharply forced crease.

Compare the whole form with the certified cap, including the other face. A small bent disk and a nickel on a dime blank are not automatically the same compound error.

 

13. 1971 Jefferson Nickel The Design on a Smaller or Different Blank

The nickel design can extend beyond a blank intended for another denomination. Copper-cent examples include ordinary strikes, double strikes, and a reported fifteen-percent off-center strike.

A Philadelphia nickel was struck forty-five percent off center on a dime blank. A separate Denver dime-blank example was double struck.

Denver nickels are also recorded on Philippine twenty-five-sentimos blanks. Their reported weights include four grams and 3.9 grams on different specimens.

These are different starting blanks, not merely different colors of normal nickel metal. A copper-coated nickel can imitate the appearance of a cent-blank error without sharing its size or weight.

Estimated Value

The Philadelphia forty-five-percent off-center dime-blank example, graded PCGS MS63, sold for $480 in October 2022. Estimate $200–$1,000 for confirmed cent- or dime-blank pieces, with stronger combinations reaching an estimated $1,000–$3,000.

The foreign-blank examples fit an estimated $500–$1,500 range depending on condition. These figures value complete coins; repeated strikes or displacement should be assessed with the wrong blank rather than priced as separate objects to add together.

How to Identify

Record the weight before assigning a denomination: original cent blanks were about 3.11 grams, and dime blanks about 2.27 grams. The documented double-struck dime example is listed at 2.3 grams, while the Philippine specimens have separate four-gram and 3.9-gram measurements.

Calipers can compare the outline with a normal nickel’s 21.2 millimeters. A scale reading should also be compared with the nickel standard of 5 grams.

Use a 10× magnifier to inspect the plain edge, truncated lettering, and any overlapping impressions. Surface plating does not explain naturally missing outer design on a smaller blank.

Preserve each coin’s own date, mintmark, and measurements in the photographs. Do not transfer one specimen’s actual weight to another similar-looking example.

 

14. 1971 Jefferson Nickel A Proof Coin Missing Its S Mintmark

The rare missing S belongs to a Proof, a specially made collector coin, not an ordinary nickel from circulation. Philadelphia nickels legitimately carried no mintmark in 1971.

At San Francisco, one Proof stamping tool lacked the S that should have been punched into it. Coins made from that tool therefore had no mintmark.

Their collector finish is part of the identification, although handling can spoil it. An ordinary bright nickel is not transformed into a No S Proof by having an empty mintmark space.

The missing letter must be original, rather than removed from a normal Proof.

Estimated Value

A PCGS PR69 Deep Cameo example brought $7,637.50 in 2016. Deep Cameo describes strong contrast between frosted raised design and mirrored flat areas.

Estimate $700–$2,000 for authenticated genuine examples with more marks or weaker contrast and $2,000–$10,000 for exceptional pieces. These are condition-based estimates for the No S Proof only; ordinary no-mintmark Philadelphia nickels do not belong in the range.

How to Identify

Establish the Proof manufacture before checking the empty mintmark space. Compare its mirrored flat surfaces and sharp design with a genuine 1971-S Proof, rather than with a polished circulation nickel.

Keep certified pieces in their holders. On a loose example, a scale and calipers should show roughly 5 grams and 21.2 millimeters, with a plain edge.

Inspect the area below the date through a 10× magnifier for scratches, disturbed texture, or a shallow depression from removing an S.

Compare both faces for polishing that could imitate a mirror finish. Handling damage may reduce the finish of a genuine Proof, so bright surfaces alone cannot settle the question.

Have the missing mintmark authenticated as part of the complete Proof coin before using No S prices.

 

Conclusion

Estimated prices of $5–$10,000 span these 1971 nickel errors, but the identification must come before the price. A missing S matters on a genuine Proof, while a missing mintmark is normal on a Philadelphia circulation coin.

For other candidates, preserve the original surfaces and compare both sides. Record weight and size when safe, and keep later damage separate from the Mint mistake you are trying to identify.
