Denver Mint
 The Denver Mint is a branch of the United States Mint that struck its first coins on February 1 1906. The mint is still operating and producing coins for circulation as well as mint sets and commemorative coins. Coins produced at the Denver Mint bear a D mint mark (not to be confused with the mark of the Dahlonega Mint). The Denver Mint is the single largest producer of coins in the world.[citation needed]
