For most people, a dime is simply a ten-cent coin used in everyday transactions. However, certain rare and valuable dimes still exist in circulation today, and some of them can be worth thousands—or even hundreds of thousands—of dollars. Whether due to minting errors, historical significance, or limited production, these dimes have become highly sought after by collectors.
Here’s a breakdown of 10 of the most valuable American dimes that could be hiding in your pocket change.
1. 1916-D Mercury Dime
- Mintmark: “D” (Denver)
- Estimated Value: $1,000 – $20,000+
- Why It’s Valuable: This dime had an extremely low mintage of just 264,000 coins, making it the rarest of the Mercury dimes. High-grade versions, especially those with a Full Bands designation, are worth a premium.
2. 1968 No-S Roosevelt Dime (Proof Error)
- Mintmark: None (San Francisco Mint Error)
- Estimated Value: Up to $45,600
- Why It’s Valuable: Proof dimes from the San Francisco Mint should have an “S” mintmark, but a few were mistakenly minted without it. This error makes them incredibly rare.
- Check coin authenticity: PCGS
3. 1982 No-P Roosevelt Dime
- Mintmark: None (Philadelphia Mint Error)
- Estimated Value: Up to $15,000
- Why It’s Valuable: This was the first year Philadelphia dimes were supposed to carry a “P” mintmark, but some coins were mistakenly struck without it, making them a highly valuable error coin.
4. 1975 No-S Roosevelt Dime (Proof Coin)
- Mintmark: None (San Francisco Mint Error)
- Estimated Value: Over $500,000
- Why It’s Valuable: Only two of these proof dimes are known to exist without the “S” mintmark, making it one of the rarest and most expensive U.S. coins.

5. 1942/1 Mercury Dime (Overdate Error)
- Mintmark: Various (Philadelphia and Denver)
- Estimated Value: $2,500 – $20,000+
- Why It’s Valuable: A misstamped die caused the 1941 date to overlap with the 1942, creating a visible overdate error, making it a valuable collector’s item.
6. 1964-D Doubled Die Reverse Roosevelt Dime
- Mintmark: “D” (Denver)
- Estimated Value: $1,500 – $5,000
- Why It’s Valuable: This doubling error on the reverse side, particularly on the torch and lettering, makes it a desirable error coin.
7. 1996-W Roosevelt Dime (50th Anniversary Issue)
- Mintmark: “W” (West Point)
- Estimated Value: $3,000+
- Why It’s Valuable: The West Point Mint struck these dimes to commemorate 50 years of the Roosevelt dime. While not an error, low production numbers make it highly collectible.
8. 1970-S Proof Roosevelt Dime with Doubled Die Obverse
- Mintmark: “S” (San Francisco)
- Estimated Value: $1,500 – $2,500
- Why It’s Valuable: Double die errors cause parts of the coin’s design to appear duplicated, increasing collector demand.
9. 1999 Broadstruck Roosevelt Dime
- Mintmark: Various
- Estimated Value: $300 – $1,000+
- Why It’s Valuable: A broadstrike error occurs when the coin is struck without a retaining collar, making it larger and misshapen. Error collectors often pay a premium for these.
10. 2000-P Dime with Missing Clad Layer
- Mintmark: “P” (Philadelphia)
- Estimated Value: $250 – $750+
- Why It’s Valuable: Some dimes were struck without their outer clad layer, exposing the copper core underneath. These mistakes make them highly desirable to error collectors.
