What is an s mint mark on a 1970 dime?

An "S" mint mark on a 1970 dime indicates that the dime was minted at the San Francisco Mint in San Francisco, California. The San Francisco Mint is one of three active mint facilities operated by the United States Mint, along with the Philadelphia Mint and the Denver Mint. Each mint facility assigns its own mint mark to thecoins it produces, with "S" being the mint mark for the San Francisco Mint. Dimes with an "S" mint mark are not as common as dimes with a "P" mint mark (indicating the Philadelphia Mint) or an "D" mint mark (indicating the Denver Mint), as the San Francisco Mint produces a smaller number of coins compared to the other two mints.
