The 15 Most Valuable Dime Coins Errors Stil in Circulation 🤑💰

Coin collecting, also known as numismatics, has always been a popular hobby for those fascinated by the history and artistry of currency.

Among the vast array of collectible coins, error coins hold a special place due to their rarity and the unique stories they tell.

Error coins are those that were minted with mistakes, whether due to mechanical malfunctions, human error, or other anomalies in the minting process.

These errors can make coins significantly more valuable than their face value.

In this article, we will explore 15 of the most valuable dime coin errors that are still in circulation today.

1. 1968 No-S Proof Dime

The 1968 No-S Proof Dime is one of the most famous error dimes.

Proof coins are specially made for collectors and usually have a distinctive “S” mint mark to indicate they were produced at the San Francisco Mint.

However, in 1968, some proof dimes were struck without this mint mark.

These dimes are extremely rare and valuable because they were produced in very limited numbers.

Collectors prize them not only for their rarity but also for their historical significance as an error coin from the proof series.

2. 1970 No-S Proof Dime

Similar to the 1968 No-S Proof Dime, the 1970 No-S Proof Dime also lacks the “S” mint mark.

These dimes were mistakenly released without the San Francisco mint mark, making them highly sought after by collectors.

The rarity of this error makes it a valuable addition to any collection.

It’s not just the missing mint mark but also the proof quality of these dimes that adds to their value.

Proof coins have a mirror-like finish and are struck multiple times to achieve high detail, making an error in this series particularly notable.

3. 1982 No-P Dime

The 1982 No-P Dime is another significant error coin.

In this case, the “P” mint mark, which denotes the Philadelphia Mint, is missing.

This error was unintentional and resulted from a mistake during the minting process.

The 1982 No-P Dime is valuable because it was the first time a coin without a mint mark was released into circulation in over a century.

This dime is a prized find for collectors, especially those interested in modern error coins.

4. 1996-W Roosevelt Dime

The 1996-W Roosevelt Dime is unique because it was the first time the West Point Mint struck dimes for general circulation.

These dimes were part of a special collector’s set celebrating the 50th anniversary of the Roosevelt dime.

Some of these dimes found their way into general circulation, making them a valuable error coin.

The “W” mint mark distinguishes these dimes, and their limited mintage adds to their desirability among collectors.

5. 1942/1 Mercury Dime

The 1942/1 Mercury Dime is a well-known error in which a 1942 die was struck over a 1941 die, resulting in a noticeable overdate.

This error is visible with the naked eye, making it an interesting and valuable find.

The overdate error coins are particularly sought after because they are visually striking and represent a clear minting mistake.

The 1942/1 Mercury Dime is one of the most famous overdate errors in U.S. coinage history.

6. 1945 Micro S Mercury Dime

The 1945 Micro S Mercury Dime features a mint mark that is smaller than usual.

This error occurred because a different punch was used to create the “S” mint mark on some dimes.

The Micro S dimes are rarer than their regular counterparts and are highly sought after by collectors.

The smaller mint mark can be difficult to spot, making the discovery of one of these dimes an exciting event for numismatists.

7. 1964-D DDO Roosevelt Dime

The 1964-D DDO (Doubled Die Obverse) Roosevelt Dime features noticeable doubling on the obverse side of the coin.

This error was caused by a misalignment during the striking process, resulting in a doubled image of the design elements.

Doubled die errors are popular among collectors due to their visual appeal and the clear evidence of a minting mistake.

The 1964-D DDO Roosevelt Dime is a valuable find, particularly in higher grades.

8. 1983-P Doubled Die Reverse Dime

The 1983-P Doubled Die Reverse Dime is another significant error coin with doubling on the reverse side.

This error affects the lettering and other design elements, making it an interesting and valuable coin.

The doubled die error on the reverse is less common than on the obverse, adding to the rarity and desirability of this coin.

Collectors appreciate the distinct appearance of the doubled features and the challenge of finding such errors in circulation.

9. 1965 Silver Roosevelt Dime

In 1965, the United States Mint transitioned from silver to a copper-nickel clad composition for dimes.

However, a few 1965 dimes were mistakenly struck on silver planchets, making them incredibly rare and valuable.

These dimes are a fascinating part of numismatic history, representing a transitional period in U.S. coinage.

The 1965 Silver Roosevelt Dime is a highly sought-after error coin due to its rarity and the historical significance of the silver-to-clad transition.

10. 1982-D Small Date Copper Dime

The 1982-D Small Date Copper Dime is an interesting error because it was struck on a copper planchet instead of the standard copper-nickel composition.

This error occurred during a period when the Mint was experimenting with different compositions for coinage.

The small date variety adds to the uniqueness of this error coin, making it a valuable and rare find.

Collectors are particularly interested in these transitional errors, as they highlight changes in the minting process.

11. 1999-P Broadstruck Dime

A broadstruck dime is one that was struck without the retaining collar that normally keeps the coin’s edges in shape.

As a result, the coin expands and flattens out, creating a broader than normal appearance.

The 1999-P Broadstruck Dime is an example of this type of error.

These coins are valued by collectors for their unusual appearance and the minting mistake they represent.

The broadstrike error can occur with any coin, but finding a dime with this error is particularly intriguing for numismatists.

12. 1975 No-S Proof Dime

The 1975 No-S Proof Dime is another rare and valuable error coin.

Like the other No-S Proof Dimes, this coin was mistakenly struck without the “S” mint mark that indicates it was produced at the San Francisco Mint.

These coins were not meant for general circulation and were part of proof sets.

The absence of the mint mark on a proof coin is a significant error, making the 1975 No-S Proof Dime a prized addition to any collection.

13. 1968-D Repunched Mint Mark (RPM) Dime

The 1968-D RPM Dime features a repunched mint mark, where the “D” mint mark has been struck more than once, resulting in a noticeable doubling effect.

This error occurred when the mint mark punch was not properly aligned, and the error was not corrected before the coin was struck.

RPM errors are popular among collectors due to their clear visual evidence of a minting mistake. The 1968-D RPM Dime is a valuable find, particularly in higher grades.
