The following are some of the most valuable dimes:
* 1943-S Mercury dime: This dime is worth about $200 in good condition. It is a rare coin, with only about 10,000 minted.
* 1955-D Mercury dime: This dime is worth about $100 in good condition. It is also a rare coin, with only about 1.2 million minted.
* 1964-D Roosevelt dime: This dime is worth about $50 in good condition. It is the last year that dimes were minted in 90% silver.
