In this article, we’ll dive into the fascinating stories behind three of the most valuable dimes still in circulation today.

Overview: Top 3 Most Valuable Dimes
| Coin Name | Year | Defining Feature | Estimated Value |
| 1916-D Mercury Dime | 1916 | Low mintage from Denver Mint | $10,000 to $100,000+ |
| 1945 Micro-S Mercury Dime | 1945 | Tiny “S” mintmark caused by a die error | $1,000 to $10,000+ |
| 1982 No-Mintmark Roosevelt Dime | 1982 | Missing “P” mintmark from Philadelphia Mint | $500 to $3,000+ |
1. 1916-D Mercury Dime: A Collector’s Holy Grail
The 1916-D Mercury Dime stands as a landmark coin in U.S. history and a prized possession for collectors. This particular dime was minted in Denver, but with only 264,000 produced, it became one of the lowest-mintage coins in the Mercury Dime series.
Collectors prize this dime not only for its rarity but also for its design and historical significance. The “D” mintmark can be found on the reverse side of the coin, near the base of the olive branch. Even heavily circulated versions are valuable, often selling for thousands of dollars. Coins in pristine, uncirculated condition, however, have been known to fetch over $100,000 at auctions.
This dime’s scarcity and appeal make it one of the most valuable dimes in American coinage. If you happen to come across one, hold onto it—it’s a piece of history and an incredible investment.
2. 1945 Micro-S Mercury Dime: An Error That Created Value
Minting errors often produce some of the most interesting coins, and the 1945 Micro-S Mercury Dime is no exception. This coin, produced at the San Francisco Mint, features a tiny “S” mintmark that resulted from a die engraving error.
This unique feature occurred during the final year of the Mercury Dime series, adding to the coin’s appeal for collectors. Depending on its condition, a 1945 Micro-S Mercury Dime can be worth anywhere from a few hundred dollars to over $10,000.
To spot this dime, use a magnifying glass to examine the mintmark on the reverse side. If the “S” appears smaller than on other dimes from the same year, you could be holding one of the most intriguing valuable dimes still in circulation.
3. 1982 No-Mintmark Roosevelt Dime: A Modern Rarity
Even modern coins can become valuable through unexpected minting errors, as demonstrated by the 1982 No-Mintmark Roosevelt Dime. This coin was struck at the Philadelphia Mint but mistakenly released without the traditional “P” mintmark.
What makes this coin particularly special is that it’s the first dime from the Philadelphia Mint issued without a mintmark since the practice began in 1980. This rare oversight was corrected quickly, making the remaining error coins highly sought after by collectors.
A 1982 No-Mintmark Roosevelt Dime in excellent condition can sell for hundreds to thousands of dollars. To identify this coin, check the obverse side above the date—if there’s no mintmark, you’ve found a true rarity among valuable dimes.
How to Spot Valuable Dimes in Your Collection
Discovering a rare coin in your change might seem unlikely, but it’s not impossible. Here are some tips to help you identify valuable dimes:
- Inspect Mintmarks Carefully: Missing or unusual mintmarks, like the Micro-S or no-mintmark varieties, can indicate significant value.
- Check Key Years: Coins from notable years like 1916, 1945, or 1982 are worth a second look.
- Evaluate Condition: Coins with minimal wear are often worth much more.
- Use a Magnifying Glass: Subtle details, like a small mintmark or its absence, can make all the difference.
- Research Online: Cross-reference your findings with reliable coin-collecting websites or guides.
Why Are These Dimes So Valuable?
The high value of these dimes is rooted in three key factors:
- Rarity: Coins with low production numbers or errors are incredibly difficult to find, driving their value up significantly.
