Dimes may seem small and of little worth due to their size and low face value, but a select few are worth far more than their face value—some can fetch thousands, or even hundreds of thousands of dollars. These rare dimes are true treasures, sought after by collectors worldwide.
In this article, we’ll take a closer look at three of the most valuable dimes still circulating today. From minting mistakes to low production runs, these coins stand out for their unique features and historical significance. Whether you’re a casual coin enthusiast or a seasoned collector, knowing what makes these dimes so valuable can help you spot potential treasures in your spare change.
Top 3 Most Valuable Dimes: Overview
| Coin Name | Year | Key Feature | Estimated Value |
|---|---|---|---|
| 1916-D Mercury Dime | 1916 | Low mintage from the Denver Mint | $10,000 to $100,000+ |
| 1945 Micro-S Mercury Dime | 1945 | Tiny “S” mintmark due to die error | $1,000 to $10,000+ |
| 1982 No-Mintmark Roosevelt Dime | 1982 | Missing “P” mintmark from Philadelphia | $500 to $3,000+ |
1. 1916-D Mercury Dime: A Coin of Rare Rarity
The 1916-D Mercury Dime is not just a rare find, it’s a true icon in the world of coin collecting. Produced in Denver with a mere 264,000 dimes minted, this coin stands as one of the most scarce in the Mercury Dime series.
Collectors value the 1916-D not only for its low mintage but also for its design and historical importance. The “D” mintmark, located on the reverse near the olive branch, makes this dime easy to identify. Even dimes that have been heavily circulated can command a price in the thousands. Uncirculated versions of the 1916-D have been known to fetch over $100,000 in auctions, making it one of the most sought-after dimes in the market.
If you come across one of these, hold onto it—it’s a piece of American numismatic history and a potentially lucrative investment.
2. 1945 Micro-S Mercury Dime: A Minting Error Turned Treasure
Minting errors often give birth to some of the most fascinating and valuable coins, and the 1945 Micro-S Mercury Dime is no exception. This dime, produced at the San Francisco Mint, is marked by an unusually tiny “S” mintmark, which resulted from a die error during the minting process.
This small flaw adds to the coin’s desirability for collectors. While this error was rare, it occurred in the final year of the Mercury Dime series, making the 1945 Micro-S even more intriguing. Depending on its condition, a 1945 Micro-S can be worth anywhere from a few hundred to over $10,000.
To spot this rare dime, use a magnifying glass to examine the mintmark on the reverse side. If the “S” appears noticeably smaller than typical dimes from the same year, you might be holding a significant piece of numismatic history.
3. 1982 No-Mintmark Roosevelt Dime: A Modern-Day Rarity
Even more recent coins can hold surprising value, as seen with the 1982 No-Mintmark Roosevelt Dime. This coin was struck at the Philadelphia Mint but was mistakenly released without the usual “P” mintmark.

What makes this error particularly special is that it marked the first time a dime from the Philadelphia Mint was released without a mintmark since the practice was introduced in 1980. After this mistake was discovered, the production was quickly corrected, making the remaining coins highly coveted by collectors.
A 1982 No-Mintmark Roosevelt Dime in excellent condition can fetch hundreds to thousands of dollars. To identify one, check the obverse side above the date—if there’s no mintmark, you’ve found a rare gem among modern coins.
