Rare 1950 Dime Errors (List & Pictures)
The small mintmark on a 1950 dime deserves a careful look: an upright S can hide an earlier upside-down S. A superbly preserved example brought $646.25 at auction in June 2016.
Estimated values for the eight groups of 1950 dime errors run from $15–$800. Work around the coin’s outline first, then study surface marks and the small doubled details.
| What catches your eye? | Error to investigate | Estimated value |
|---|---|---|
| Wide border with complete designs | Broadstrike | $75–$500 |
| Blank crescent and incomplete designs | Off-center strike | $75–$750 |
| Unusually thin, light coin | Thin planchet | $100–$500 |
| Raised patch meeting the rim | Rim cud | $50–$600 |
| Fine raised line | Die crack | $15–$100 |
| Interrupted back-side detail | Strike-through | $25–$300 |
| Extra mint-letter curves | Repunched or overpunched mintmark | $25–$800 |
| Repeated letter or design outlines | Doubled die | $30–$800 |
Normal 1950 dimes are 90% silver, weigh 2.50 g, and measure 17.9 mm across a grooved edge. A scale, calipers, low-angle light, and a 10× magnifier provide useful checks for an accessible coin.
Use recorded measurements for coins sealed in grading holders. The quoted ranges concern whole coins, including their condition, rather than amounts automatically added to another price.
1. 1950 Dime An Expanded Border: 1950-D Dime Broadstrike Error
Start by reading the lettering around both faces of a wide-looking dime. If the entire design survives within an enlarged border, a broadstrike is a possibility.
The collar normally confines the blank’s edge while the dies stamp it. Without that restraint, silver can spread outward beyond the usual diameter.
How to Identify
Measure across several directions and examine the edge for incomplete grooves. Look for naturally formed detail rather than letters crushed by pressure applied after minting.
The documented Denver example is NGC MS63 Full Bands. MS63 describes an unworn coin with noticeable marks; Full Bands refers to the clear separation of horizontal bands on the torch.
That torch detail concerns strike quality and does not authenticate the broadstrike by itself. The expanded outline and complete designs remain the central checks.
What It’s Worth
Genuine examples have an estimated $75–$500 range across different conditions. A clean, visibly expanded coin usually offers a stronger comparison than a worn or damaged piece.
A 1946 broadstrike graded NGC MS66 Full Torch sold for $258.50 in October 2012. Its date and finer preservation differ from the 1950-D specimen, whose sale amount is not supplied here.
2. 1950 Dime A Crescent Without a Design: Reported 1950 Off-Center Strike Error
Some wide-looking errors have lost part of the picture rather than keeping it complete. On an off-center strike, the blank was out of position and only part of it entered between the stamping tools.
The resulting plain metal remains attached beside the incomplete design. Year guides include this error for 1950 without establishing one specimen’s percentage or direction.
How to Identify
Photograph the entire coin on both sides and find the surviving date. Both designs should show the effect of the displaced blank; a shift confined to one face may involve one die instead.
Inspect the plain crescent for scraping or grinding. An original unstruck area has a different origin from finished detail removed later.
A clipped blank lacks metal at its opening. An off-center dime retains metal where the design failed to land, and its mintmark may be lost if that part of the design missed the blank.
What It’s Worth
Readable-date silver examples have an estimated $75–$300 range for modest offsets and $300–$750 for bold, attractive errors. These are comparison ranges for the reported category.
A 1964 dime struck sixty percent off center brought $134 in December 2025 in ANACS MS65. That other-year result shows why percentage alone cannot dictate value.
3. 1950 Dime Normal Width but Too Little Weight: 1950-S Thin Planchet Error
The 1.74 g weight recorded for a 1950-S dime is well below the usual silver standard. It was cataloged as struck on a thin planchet, meaning the prepared metal blank was too thin.
Reduced metal thickness can affect the way the design fills out between the dies. It does not establish that the blank was intended for a foreign coin.
How to Identify
Check weight together with thickness at several points. A near-normal diameter can coexist with a thin blank, so the outside measurement alone is insufficient.
Examine the surfaces and edge for filing marks or chemical pitting that could explain missing metal. The listed 1.74 g specimen received an NGC MS65 grade, indicating well-preserved, unworn condition.
What It’s Worth
An authenticated thin-blank dime has an estimated $100–$500 range. Weight difference, visible striking effects, and surface quality all influence a comparison.
A 1955-S thin-planchet dime weighing 2.1 g sold for $107 in October 2021 in NGC MS64. The lower weight of the 1950-S does not create an automatic price multiplier over that sale.
4. 1950 Dime A Raised Patch at the Bottom Rim: Reported 1950-D Cud Error
Turn the torch upright and look below its handle. A reported Denver example has a raised patch connected to the reverse rim around six o’clock.
This type of rim break is called a cud. A piece missing from the die’s edge creates a space into which the coin’s metal can rise during striking.
How to Identify
Follow the patch’s connection to the rim and determine whether normal design was replaced there. A small isolated lump between letters belongs to a different kind of die break.
Check the edge and opposite face for crushing from a later impact. Added solder or dirt can also make a raised patch, often with a separate boundary over finished detail.
What It’s Worth
Small genuine cuds on circulated coins have an estimated $50–$200 range, while larger, clear examples can reach approximately $200–$600. The estimates use similar silver Roosevelt rim breaks.
No completed sale is claimed for the reported six-o’clock coin. The size and clarity of the original break matter more than how conspicuous an unrelated rim injury appears.
5. 1950 Dime A Ridge Across the Hair: 1950-D Die Crack Error
A narrow raised line can reveal damage to the die without any crack through the coin itself. Silver entering a crack in the stamping tool leaves a ridge on the finished dime.
Reports mention lines in Roosevelt’s hair and, separately, a crack near one o’clock. These locations should not be combined into an invented path on one coin.
How to Identify
Set the light low enough to see whether the mark stands above the field or cuts below it. A scratch usually produces a groove, while a die crack supplies raised metal.
Photograph the whole route with nearby hair and lettering visible. A genuine cracked coin, a bent edge, or displaced metal beside a deep scratch requires another explanation.
What It’s Worth
Small original die cracks carry an estimated whole-coin value of $15–$100, from circulated examples to modest unworn coins. This range is based on comparable silver Roosevelt dimes.
A faint line may add little, whereas a clearly visible ridge is easier to collect and display. No individual 1950-D crack sale is supplied.
6. 1950 Dime Missing Detail on the Back: 1950 Dime Strike-Through Error
Harbor Coin listed a Philadelphia dime with a reverse strike-through in PCGS MS64. The affected side is the back with the torch, but the brief record does not identify the trapped material or its exact position.
Something between the die and blank can interrupt the transfer of design. The resulting weak patch or impression therefore formed while the coin was being struck.
How to Identify
Compare the interrupted detail with sharp neighboring letters on a normal dime. Keep the surrounding area in the photograph so that general wear is not mistaken for a localized event.
Inspect any depression for a displaced lip, scraping, or an opposite-face impact mark. A later blow damages completed detail and may leave evidence beyond the hollow itself.
What It’s Worth
Small clear strike-throughs have an estimated $25–$100 range, with larger distinctive impressions around $100–$300. Attractive surrounding surfaces strengthen the comparison.
The listed MS64 coin has no completed sale amount used here. Its unworn grade and reverse attribution do not justify naming grease, wire, or another material that the record does not specify.
7. 1950 Dime Extra Curves Beneath S or D: 1950 Repunched and Overpunched Mintmarks Error
Find the small letter left of the torch base. On the recognized 1950-S FS-501, traces of an upside-down S survive beneath the corrected upright S.
Mint workers punched these letters into dies by hand, allowing earlier positions to remain. Although older descriptions called this S-mint pattern S over D, S over inverted S is the accepted explanation for this particular variety.
Denver reports cover D/D repunching and a separate proposed D over S. Each needs its own letter-shape evidence.
How to Identify
For the S variety, match the remaining inverted curves to an attributed FS-501. For a Denver coin, establish whether the earlier outline belongs to another D or a different letter before choosing a label.
A bump alone is not enough to identify an overmintmark. Famous 1950 quarter varieties cannot supply the missing evidence for a dime.
What It’s Worth
Ordinary clear repunching has an estimated $25–$250 range, with fine S-over-inverted-S coins around $400–$800. A separately verified Denver overmintmark has a conditional estimate of $50–$500.
An exceptional PCGS MS67+ S-over-inverted-S sold for $646.25 in June 2016. Its unusually high state of preservation is an essential part of that comparison.
8. 1950 Dime Repeated Letter and Torch Outlines: 1950 Dime Doubled Die Error
The Denver reverse variety FS-801 concerns extra design detail around lettering, the torch, and leaves. A doubled pattern in the die can repeat those features across coins made with that tool.
A separate Philadelphia collector report concerns doubling on the front. It does not establish the Denver reverse pattern on a Philadelphia coin or doubling on both faces of one example.
How to Identify
Compare several reverse features with an identified FS-801 when examining a Denver coin. Repeated raised separation is more persuasive than one thick letter or a flat shelf from movement during striking.
The Philadelphia report needs a separate front-side match. These circulation issues also require different comparisons from specially made Proof coins.
What It’s Worth
Ordinary clear doubled dies have an estimated $30–$300 range, while exceptional examples can support a $600–$800 comparison. The Philadelphia report needs identification before any variety premium can be assigned.
A 1950-D FS-801 graded CACG MS64 brought $100.12 in February 2026. A separate NGC MS65 example has a $712.49 eBay Best Offer record from November 2022, an exceptional transaction rather than a routine auction benchmark.
Conclusion
A wide outline, low weight, raised ridge, and second mint-letter curve point toward different checks. Begin by deciding which feature is actually present before applying a price range.
For 1950 dimes, the strongest comparisons keep the mint, condition, and exact error together. The $15–$800 estimates include ordinary examples and exceptional grades, while the reported categories still require evidence that a particular coin matches the claim.
