While dimes might seem like small change to most, some of these ten-cent pieces hold significant value among collectors and coin enthusiasts. Certain dimes still in circulation or discovered in pocket change can be worth hundreds, even thousands, of dollars. Their rarity, historical significance, mint errors, or unique characteristics make them highly prized.
This article highlights ten of the most valuable American dimes still potentially in circulation today.
1. 1894-S Barber Dime
Estimated Value: $1.5 Million
One of the rarest and most sought-after coins in American numismatics, only 24 of these dimes were ever minted in San Francisco, and just nine are known to still exist. The 1894-S Barber Dime is considered a collector’s dream. Though unlikely to be found in everyday circulation, stories have circulated of examples being discovered in old coin collections or estate sales.
2. 1916-D Mercury Dime
Estimated Value: $1,000 to $10,000+
This dime was the first in the Mercury dime series and was minted in Denver with a low mintage of just 264,000. Its popularity stems from both its age and limited supply. If you find one with the “D” mintmark on the reverse side, located to the left of the fasces, you may have a valuable coin on your hands.
3. 1942/1 Mercury Dime (Philadelphia Mint)
Estimated Value: $400 to $2,000+
This variety was created when a 1942 die was accidentally struck over a 1941 die, resulting in visible doubling of the date. These overdate errors are rare and are popular among collectors. Make sure to check the date carefully, as the “1” under the “2” is quite distinct when magnified.
4. 1942/1-D Mercury Dime (Denver Mint)
Estimated Value: $500 to $3,000+
Similar to its Philadelphia counterpart, this Denver-minted error is even more scarce and therefore potentially more valuable. Both versions are popular due to their well-documented minting error and relative scarcity in high-grade condition.
5. 1873-CC No Arrows Seated Liberty Dime
Estimated Value: Over $400,000
With only one known example in existence, this Carson City–minted dime is one of the most elusive coins ever struck in the U.S. The “No Arrows” version is differentiated by the absence of arrow marks beside the date, a detail that helps identify this ultra-rare coin. Though technically not in modern circulation, it remains legendary in the world of coin collecting.
6. 1982 No Mintmark Roosevelt Dime
Estimated Value: $50 to $300+
In 1982, some dimes produced at the Philadelphia Mint were released without a mintmark due to a manufacturing oversight. The missing “P” mintmark on the obverse is the key identifying feature. These errors are relatively common in circulated condition but can be worth significantly more if found in uncirculated or mint state.
7. 1996-W Roosevelt Dime
Estimated Value: $20 to $100+
This dime was issued by the West Point Mint in a special collector’s set, and only about 1.4 million were minted. While these were not intended for circulation, some have ended up in pocket change over the years. The “W” mintmark is located just above the date on the obverse.
8. 1874-CC Arrows Seated Liberty Dime
Estimated Value: $5,000 to $15,000+
With a mintage of just over 10,000, this Carson City dime is a prized coin among those who collect Old West–era currency. The arrows on either side of the date signify a weight change in the coinage and help distinguish this version from others.
9. 1921 Mercury Dime
Estimated Value: $50 to $500+
Although not as rare as the 1916-D, the 1921 Mercury Dime had a relatively low mintage from both the Philadelphia and Denver Mints. As a result, finding one in circulation today is rare, and uncirculated examples are highly valued.
10. 1975 No-S Roosevelt Dime (Proof Only)
Estimated Value: Over $500,000
This ultra-rare error appeared in proof sets produced by the San Francisco Mint. The “No-S” error indicates the coin was struck without the “S” mintmark, which should have been included on all proof dimes. Only two examples are known to exist, making it one of the most valuable modern coins.
Tips for Identifying Valuable Dimes
While these dimes are rare, it’s still possible though improbable to find them in your spare change, especially the more recent varieties like the 1982 No Mintmark and the 1996-W Roosevelt Dime.
Here are a few tips:
- Check mintmarks: The mintmark can usually be found near the date on the obverse or on the reverse depending on the design.
- Inspect for errors: Overdates, missing mintmarks, or unusual markings can increase a dime’s value significantly.
- Condition matters: Coins in mint or near-mint condition fetch the highest prices.
Final Thoughts
Most of these valuable dimes are unlikely to turn up in your daily cash transactions, but it’s worth checking your change. With knowledge, patience, and a bit of luck, a rare and valuable coin might just find its way into your pocket.
Coin collecting remains a popular hobby not only for its historical interest but also for the potential of uncovering rare treasures. Whether you’re an experienced numismatist or a casual collector, keeping an eye on your dimes might just pay off in a big way.
