1958 Half Dollar Error List with Pictures
A 1958-D half struck on a silver quarter blank sold for $1,440 in December 2020. It weighed just 6.3 grams, about half as much as a normal Franklin half.
The 1958 Franklin half dollar errors below have estimated values from $50 to $6,250, including exceptional high-grade varieties. Many look normal until you inspect a tiny mark or the edge.
Read on to find the useful clues. The Liberty Bell’s familiar crack is part of the normal design.
1. 1958 Franklin Half Dollar Goiter Neck Feature (Estimated Up to $250)
An added swelling near Franklin’s neck or chin gives the reported Denver feature its Goiter Neck nickname. Compare it with the normal portrait before treating it as extra metal.
A year guide suggests a gouge in the die as the cause. The die is the steel tool that stamps the coin.
The guide does not give a numbered variety or independently established cause. A cut in the tool could leave a raised shape on the coin.
Metal added later or pushed up by damage can look similar. The nickname tells you where to look, but does not settle what happened.
Estimated Value
Estimate $50–$250 for a convincing Mint-made neck feature on an worn coin or one with no circulation wear but visible marks. This is not a recorded Goiter Neck sale.
A different 1958 feature, the recognized FS-402 clash, brought a reported $450 in MS66 in January 2023. That provides a broader comparison for collector interest.
It does not give the neck feature the same catalog identity or value. A clear raised shape and original surfaces are needed for a useful comparison.
How to Identify
Compare the neck and lower jaw with a normal 1958-D under the same light. Shadows can make the normal portrait appear swollen.
Use a 10× magnifier around the suspected extra metal. Check for a seam, solder-like texture, or a nearby dent that could explain it as later damage.
Find the D above the bell’s wooden support and inspect the edge ridges. A scale should be compared with 12.50 grams and calipers with about 30.6 millimeters.
Keep both a full portrait image and a close-up. The useful first clue is a raised shape that joins the original neck surface naturally, rather than a shadow or added blob.
2. 1958 Franklin Half Dollar Obverse Lamination (Estimated Up to $300)
A band runs across the upper part of Franklin’s head on a reported 1958-D lamination. It extends into the smooth background on both sides.
Jim’s Coins described it as running from about 3:30 to 9:30 on a coin without circulation wear. The location is more specific than a general report of peeling silver.
Lamination means a weak layer within the alloy has separated. A flap may remain attached, or the metal beneath may be exposed.
The listing does not establish which parts remain attached on this example. Examine the opening rather than assuming that the whole band has peeled away.
Estimated Value
Visible local laminations have an estimated range of $50–$300 across circulated and ordinary uncirculated Franklin halves. A broad band across the portrait is easier to notice than a tiny seam.
A 1957 NGC MS63 lamination sold for $74.49 including the buyer’s fee at Pristine in January 2021. That different-year result supports a modest example’s value.
The 1958-D listing gives no price used here. Neither record fixes the value of a larger attached flap.
How to Identify
Follow the reported band across the upper head and into the smooth areas on both sides. Light from the side can show whether it opens as a layer.
A 10× magnifier should reveal a separating border, not just a scratch with metal pushed alongside it. Leave any attached flap in place.
Photograph the opening and inspect the edge ridges for another view of the alloy. Nearby design should fit the natural separation rather than show later cutting.
A scale may read below 12.50 grams if metal is gone, while an attached layer may preserve the weight. Check about 30.6 millimeters with calipers.
The peeling border across the head is the first feature to confirm, not the band’s dark color alone.
3. 1958 Franklin Half Dollar Clipped Planchets (Estimated Up to $400)
A tiny clip near eight o’clock appears on a Philadelphia half listed as ANACS MS65. Separate records describe straight clips and curved gaps on other 1958 coins.
One specialist describes a six-percent straight clip near 8:30, interrupting IN, part of G, and UNITED on the back. Heritage cataloged another straight clip at four percent.
These are different examples. Their measurements should not be exchanged.
All began with missing metal before the designs were struck. The incomplete blank shaped how nearby letters and the rim formed, unlike a later cut through a finished coin or a complete blank spreading during striking.
Estimated Value
Estimate $60–$400 for genuine clips, depending on size, condition, and surviving detail. A historical sale needs one important qualification.
Heritage’s October 2021 lot sold for $120 and contained two coins: a 1958 PCGS MS63 four-percent straight clip and a 1961 ANACS MS63 straight clip. The total belongs to both.
It cannot be assigned entirely to 1958 or split into proven individual prices. A clearer or larger clip still needs its own comparison.
How to Identify
Inspect the two places where the gap meets the normal rim with a 10× magnifier. Look for nearby lettering and rim metal formed around an already incomplete blank.
Fresh saw marks or filing through finished details suggest a later cut. Match a straight clip with a straight-clip example, not a curved bite.
On the six-percent report, use the interrupted lettering to check its location. Opposite-rim weakness can help but is not equally obvious on all clips.
Use calipers across intact parts against 30.6 millimeters and a scale against 12.50 grams, then inspect surviving edge ridges. Matching original struck borders at the gap on both sides are the most useful first clues.
4. 1958 Franklin Half Dollar Repunched D Mintmark (Estimated Up to $500)
The D above the bell’s wooden support can retain a piece of an earlier mintmark impression. A worker punched the letter into the stamping tool again in a slightly different position.
The year guide reports repunched mintmarks without a particular direction or specialist number. It does not establish a northward, downward, or tilted variety.
A candidate needs a clear comparison of the whole D. The extra shape should look like part of that same letter.
A flat ledge caused by movement during striking is different. It can make a mintmark appear doubled without preserving an earlier hand-punched impression.
Estimated Value
Estimate $75–$500 for clearly identified minor repunching on ordinary collectible examples. The broader Franklin market provides the comparison.
PCGS records a 1952-S FS-501 MS65 transaction at $590 in May 2021. That earlier coin has its own mintmark variety and condition.
It is not a sale of a 1958 half. A visible second letter shape and original surfaces matter more than an unclear edge that appears unusual only under extreme enlargement.
How to Identify
Center a 10× magnifier on the D above the bell. Follow its straight stem and curved bowl, then look for a separate piece repeating that letter shape.
Move the light to separate a real raised curve from a reflection. Check the smooth background for scratches or pushed-up metal.
Keep a full back photograph with the close-up. Match a confirmed half-dollar example from the same year and mint.
Inspect the edge ridges and use a scale and calipers against 12.50 grams and about 30.6 millimeters. Start with the extra D-shaped curve, then match its actual position instead of assuming a direction from the date.
5. 1958 Franklin Half Dollar Obverse Doubling and Double Bar 5 (Estimated Up to $600)
An extra horizontal stroke near the top of the 5 gives the reported Double Bar 5 its name. The year guide also mentions doubled front designs.
It does not establish whether the extra bar belongs to one of those doubled dies. The two reports may overlap.
A doubled die is a stamping tool with repeated design details that appear on later coins. An isolated tool flaw or a flat ledge from striking can look different.
Both reports remain in this section without assuming two separate varieties. A nickname does not prove that the entire front was doubled or re-engraved.
Estimated Value
Estimate $75–$600 for a supported minor front-side variety with clear extra detail. This is one whole-coin range, not two premiums added for possibly overlapping reports.
The recognized 1958 FS-402 clash brought a reported $450 in MS66. That shows interest in an established same-year feature, but it has a different cause.
Its price does not prove doubling or a Double Bar 5 sale. The actual added shape needs to be identified before using the estimate.
How to Identify
Put a normal 1958 date beside the candidate at the same enlargement. With a 10× magnifier, examine the top of the 5 under matching light.
Is the extra bar rounded raised metal, a flat ledge, or a shape unrelated to the digit? Continue across the date and front lettering to see whether other outlines repeat.
Those are inspection areas, not a promised list of doubled letters. One thick edge cannot establish a doubled stamping tool.
Check the edge ridges and compare 12.50 grams and about 30.6 millimeters with a scale and calipers. The useful first decision is whether the extra bar matches a repeatable Mint-made detail on another verified example.
6. 1958 Franklin Half Dollar Cracked Planchet (Estimated Up to $650)
This crack passes through the coin’s metal, unlike the crack drawn on the Liberty Bell. A specialist describes a 1958 example with an opening entering near 6:30 on the front.
It crosses the lower motto and continues into Franklin’s portrait. On the back, it passes the first T in STATES toward the right side of the bell’s wooden support.
The March–April 2019 ErrorScope article identifies the crack as present before striking. The design was formed around an already weakened blank.
That differs from a raised ridge copied from a cracked stamping tool or a coin bent until it split later.
Estimated Value
Estimate $100–$650 for a genuine crack present before striking on an otherwise ordinary collectible half. The surface around the opening matters more than its length alone.
The specialist report gives identifying details but no sale price. A separate 1960 split-blank example sold for $630 in June 2023.
That larger separation provides context near the upper end. It is not a 1958 cracked-blank sale, and the two coins should not receive an automatic identical value.
How to Identify
Trace the opening from the front rim near 6:30 through D in GOD and R in TRUST into the portrait. Then inspect the back beside the first T in STATES and the right side of the wooden support.
A 10× magnifier should show an opening in the coin, not a raised line on top of it. Check how the stamped details meet that opening.
Later bending may distort the edge ridges. Do not flex the coin to make the crack easier to see.
Use a scale against 12.50 grams and calipers against about 30.6 millimeters. The matching two-sided path and design formed around the opening distinguish this fracture from the Bell’s normal drawn crack.
7. 1958 Franklin Half Dollar Rim Cud (Estimated Up to $800)
A raised patch joined to the rim can be a cud. It forms where a piece breaks from the edge of the stamping tool.
During striking, metal enters the empty space and makes a mound instead of the intended design. The mound becomes part of the coin itself.
The year guide reports cuds without identifying an exact face, size, or clock position on a particular 1958 half. A candidate must show the correct rim connection.
A small lump inside the design is not the same thing. The crack drawn on the Liberty Bell is also normal design, not a cud.
Estimated Value
Estimate $100–$800 for modest through prominent rim cuds on circulated or lower-grade uncirculated coins. A larger area replacing clear design may attract more interest.
A 1976-D Kennedy back-side die break graded NGC MS65 sold for $256 in June 2026. It offers a recent half-dollar comparison.
That coin has a different design, metal, and break shape. The result supports a broad estimate, not a claimed 1958 sale or a fixed price for every raised patch.
How to Identify
Find where the raised patch joins the rim and note which normal details it replaces. Use a 10× magnifier to check its border for a seam around added material.
A blow to the edge can push metal inward and leave a nearby compressed area. Solder may have a different texture from the struck surface.
Inspect the opposite face for weak detail, though that clue varies with the break. Photograph both sides rather than judging the lump alone.
Normal measurements are about 30.6 millimeters with calipers and 12.50 grams on a scale. Check the unaffected edge ridges too.
The key is a naturally struck mound replacing design and joining the rim.
8. 1958 Franklin Half Dollar Proof Struck Through (Estimated Up to $1,000)
A weak patch can be especially visible against a Proof’s shiny background. Proofs are specially made collector coins, and later scratches can stand out just as strongly.
A year account reports a 1958 NGC PF64 with a strike-through. It gives no exact location or material for the obstruction.
A strike-through forms when something gets between the blank and stamping tool. The object may leave an impression or stop some details from forming.
That differs from a cut across a finished shiny surface. Wire, cloth, or grease should not be named without a shape or surviving material that supports the claim.
Estimated Value
A genuine Proof strike-through has an estimated range of $100–$1,000, depending on visibility and the remaining shiny surfaces. No original transaction is attached to the reported PF64 here.
A 1951-S NGC MS64 strike-through was recorded at $134 in April 2026. That was an ordinary circulation strike from another year.
The comparison helps frame a modest error. A clearly recognizable obstruction on an attractive Proof needs its own finish and condition comparison.
How to Identify
Check whether the mark is on the coin or on its plastic holder. Change the focus and light while using a 10× magnifier, and leave a sealed holder closed.
Inspect the boundary between shiny background and affected area. A strike-through should explain missing detail or an impressed shape, rather than a cut with metal pushed along it.
Fine scratches continuing through the patch may indicate cleaning or later abrasion. Do not infer the blocking material from brightness alone.
All 1958 Proofs are Philadelphia silver coins. For a loose example, inspect the edge ridges and compare 12.50 grams and 30.6 millimeters with a scale and calipers.
The strongest starting clue is original Proof detail interrupted by a naturally struck impression.
9. 1958 Franklin Half Dollar Partial Collar Strike (Estimated Up to $1,200)
A step in the edge can reveal a partial collar strike even when both faces look ordinary. Heritage records a 1958-D example graded NGC AU58, meaning slight wear.
The collar is the ring that holds the blank’s edge during striking. Part of the blank’s thickness remained outside that ring.
The held portion formed its edge ridges, while the exposed part could spread farther. Their meeting point can resemble a railway track.
This does not establish a particular tilt direction for the listed coin. Unlike a clip, the error changes the shape of metal without requiring a piece to be missing.
Estimated Value
Estimate $200–$1,200 for Franklin partial collar strikes across circulated and attractive uncirculated grades. Heritage’s January 2010 record lists the 1958-D NGC AU58 at $253.
That same-year result is a historical comparison, not a current fixed price. A clear edge step and clean surfaces make the feature easier to appreciate.
Polishing or later compression of the rim can reduce appeal. Compare the actual edge around the coin rather than relying on one dramatic photograph.
How to Identify
Turn the coin through a complete circle while viewing its edge. A 10× magnifier should show the ridged portion meeting the section that spread beyond the collar.
Calipers can record both levels against the normal 30.6-millimeter diameter. A scale may remain near 12.50 grams because this error spreads metal rather than removing it.
Confirm the D above the bell. Check for filing, a cut groove, or crushed ridges that might imitate the step.
A thick-looking rim in one face-on photo is not enough. The clearest first test is the original struck junction between the normally held edge and the expanded metal beside it.
10. 1958 Franklin Half Dollar Struck on a Quarter Blank (Estimated Up to $5,000)
The recorded 1958-D wrong-blank half weighs 6.3 grams. Franklin’s design was struck on a silver quarter blank instead of the larger half-dollar blank.
The blank did not have room for all the outer lettering. Heritage describes the NGC MS62 example as fairly centered, with parts of most border words remaining.
Its small size therefore comes from the wrong blank, rather than a normal half-dollar blank shifted far to one side. The date and mint remain useful clues.
Both denominations used ninety-percent silver in 1958. A silver test alone cannot separate this error from a normal half.
Estimated Value
The 1958-D NGC MS62 sold for $1,440 on December 15, 2020. Estimate $1,500–$5,000 for comparable authenticated quarter-blank errors.
The old sale is a starting comparison, not a guaranteed present price. Grade, surviving identity, and surface quality still matter.
A readable date and D help collectors identify the coin. Serious damage or much less remaining design calls for a different comparison from this fairly centered example.
How to Identify
Start with weight: the cataloged coin is 6.3 grams, close to the quarter’s 6.25 grams instead of the half’s 12.50 grams. A scale provides the first useful separation.
A quarter blank begins near 24.3 millimeters across, compared with 30.6 millimeters for a half. Use calipers to record the actual outline, allowing for spread during striking.
Under a 10× magnifier, inspect where the outer lettering ends. It should stop because the blank was too small, not because someone trimmed a complete coin.
Check surviving edge texture and confirm the date and D directly. Quarter-like weight paired with naturally incomplete half-dollar designs gives the strongest first match.
11. 1958 Franklin Half Dollar FS-402 Obverse Die Clash (Reported Up to $6,250)
Outlines on the front of the Philadelphia FS-402 come from clashed stamping tools. The front and back tools met without a blank between them.
Their contact left marks from the opposite design on the tools. Later coins then received those stray outlines alongside the normal portrait.
A full eagle or bell does not have to appear. Polishing the tool could also weaken the traces left on later coins.
PCGS recognizes FS-402 with and without Full Bell Lines. That term means the fine lines at the bell’s base are sharply defined; it describes a separate feature, not another kind of clash.
Estimated Value
Ordinary identified examples have an estimated range of $75–$450. PCGS records an MS66 marketplace result at $450 in January 2023.
The MS67 Full Bell Lines record is a reported eBay result of $6,250 in February 2021. That supports an exceptional-condition range of $2,000–$6,250.
The high result prices the complete coin. It is not a $6,250 clash premium or a guarantee from a major auction house.
How to Identify
Use a clear FS-402 photograph to locate the extra front-side outlines. A 10× magnifier and light from the side help show shallow marks that vanish under direct light.
Compare the relevant part of the back design in the correct reversed position. Random scratches across the smooth background do not establish a clash.
Confirm that no mintmark appears above the bell and inspect the edge ridges. For a loose example, use a scale and calipers against 12.50 grams and about 30.6 millimeters.
Check the bell’s fine lines separately if a price depends on Full Bell Lines. The quickest variety match is the same extra outline in the same position as the known FS-402.
Conclusion
These 1958 errors and varieties have estimated values from $50 to $6,250. Small surface flaws and exceptional high-grade clash coins belong to very different price levels.
Start with the date, mintmark, and actual shape of the feature. A real split through the coin is different from the Bell’s normal crack, just as a quarter blank differs from a clipped half-dollar blank.
Compare the whole coin’s condition before choosing a price.
