Imagine holding a small yet historic piece of silver that could be worth thousands of dollars. The Mercury Dime, minted from 1916 to 1945, is one such coin that continues to capture the fascination of collectors and investors alike. While most dimes are considered pocket change, some rare Mercury Dimes have sold for over $200,000, making them prized possessions in the numismatic world.
These dimes, made of 90% silver, feature the iconic image of Lady Liberty donning a winged cap—often mistaken for the Roman god Mercury, hence the coin’s name. The value of Mercury Dimes depends on various factors, including rarity, minting errors, condition, and historical significance. Coins with low mintage, those in near-perfect condition (especially with visible “Full Bands” on the fasces), and rare variations from different mints tend to command the highest prices.
If you’re curious about which Mercury Dimes are the most valuable in 2025, here’s a ranked list of the top fourteen, from the least to the most expensive:
14. 1931-S Mercury Dime
This coin had a lower mintage of just over 1.8 million, making it one of the more challenging Mercury Dimes to find in pristine condition. While common in circulated grades, mint-state examples fetch significant prices.
13. 1927-D Mercury Dime
The 1927-D is a rare find in higher grades due to weak strikes and circulation wear. Well-preserved pieces, especially those with Full Bands, command high prices among collectors.
12. 1919-D Mercury Dime
This dime is highly sought after due to its lower mintage and difficulty in locating well-struck examples. Finding one in top condition is a rare feat, increasing its value significantly.
11. 1942/1 Overdate Error Dime (Philadelphia Mint)
This intriguing error coin occurred when a 1941 die was mistakenly overpunched with the 1942 date. This mistake led to a valuable variety that has become a favourite among collectors.
10. 1942/1-D Overdate Error Dime (Denver Mint)
Similar to its Philadelphia counterpart, this overdate error from the Denver Mint is rarer, and examples in high grades are worth a fortune.
9. 1921 Mercury Dime
With a mintage of just over 1.2 million, the 1921 Mercury Dime is one of the key dates in the series. It’s rare to find in uncirculated conditions, making it highly valuable.
8. 1925-D Mercury Dime
This dime had a relatively low mintage and was difficult to find in well-preserved condition. Collectors pay a premium for high-grade specimens with Full Bands.
7. 1926-S Mercury Dime
One of the rarest Mercury Dimes in high grades, the 1926-S suffers from weak strikes and excessive circulation wear. Only a few examples of mint-state conditions exist today.
6. 1921-D Mercury Dime
The 1921-D is among the lowest mintage Mercury Dimes, with just over 1 million produced. Its rarity makes it one of the most desirable coins in the series.
5. 1931-D Mercury Dime
Although minted in slightly higher numbers than some earlier dimes, the 1931-D is still a rare coin, especially in uncirculated condition. Collectors actively seek this date.
4. 1916-D Mercury Dime
This is the holy grail of Mercury Dimes, particularly in mint condition. With only 264,000 pieces minted, this first-year issue from the Denver Mint is incredibly rare and valuable.
3. 1945 Micro S Mercury Dime
The 1945 San Francisco Mint released a version of the dime with a tiny “S” mintmark. This variety is highly sought after, especially in high grades with Full Bands.
2. 1920-D Mercury Dime
Although not as famous as the 1916-D, the 1920-D remains a challenging find in top condition. Its scarcity drives collectors to pay premium prices for uncirculated examples.
1. 1918-D Mercury Dime with Full Bands
Topping the list, this dime in Full Bands condition is one of the most valuable Mercury Dimes. Its rarity, historical appeal, and exceptional quality make it worth tens of thousands if not more.
