While most dimes are worth just 10 cents, certain rare varieties can be worth thousands or even millions of dollars. These valuable coins often result from minting errors, low production numbers, or historical significance. Here are ten of the most valuable American dimes that have been found in circulation:

1. 1975 No-S Roosevelt Dime

Intended as a proof coin from the San Francisco Mint, this dime lacks the "S" mint mark, making it extremely rare. Only two such coins are known to exist. One sold at auction in 2019 for $456,000.

2. 1894-S Barber Dime

The 1894-S Barber Dime is one of the most famous and valuable U.S. coins. Only 24 were minted, and just nine are known to exist today. These dimes were produced under mysterious circumstances at the San Francisco Mint. One of these coins sold for over $1 million.

3. 1916-D Mercury Dime

This coin is highly sought after by collectors due to its low mintage of 264,000. It was the lowest mintage of any Mercury dime variety. A 1916-D Mercury Dime in excellent condition can be worth up to $20,000.

4. 1942/1 Mercury Dime

This overdate error shows remnants of a 1941 date beneath the 1942, resulting from a die overstrike. A 1942/1 Mercury Dime in Mint State condition sold for $76,375 at auction in 2016.

5. 1968 No-S Roosevelt Dime (Proof)

This proof coin was meant to be made at the San Francisco Mint, but it lacks the "S" mint mark. These coins are extremely rare and highly prized by collectors. They can be worth up to $15,000.

6. 1982 No-P Roosevelt Dime

The Philadelphia Mint accidentally omitted the "P" mint mark on some dimes in 1982. These dimes are relatively common but can still fetch a pretty penny. In uncirculated condition, these coins can be worth up to $300.

7. 1996-W Roosevelt Dime

This special dime was minted at the West Point Mint to commemorate the 50th anniversary of the Roosevelt dime. It bears a "W" mint mark and was not released into general circulation. Only about 1.5 million of these dimes were produced, making it a low-mintage piece that's highly sought after by collectors.

8. 1970-S Roosevelt Dime, No Mint Mark

This proof coin was mistakenly struck without the "S" mint mark, making it a rare error. These coins are highly prized by collectors and can be worth up to $1,000.

9. 1919-S Mercury Dime

A 1919-S Mercury Dime graded MS66 with "full bands" detail recently sold for $132,000 at auction. The "full bands" refer to the distinct separation between the bands on the fasces on the reverse side, indicating a strong strike.

10. 1873-CC Seated Liberty Dime (No Arrows)

This dime is one of the rarest, with only a few known to exist. It's also one of the most valuable, with one selling for over $1 million at auction. The dime lacks the arrows in the date, which were typically used to indicate the new 90 percent silver composition of the coins at the time.
