United States Mint-Denver Branch

The Denver Mint at this address is a branch of the United States Mint that has produced circulating and collectible coinage since the current facility opened in 1906. Coins struck there carry the 'D' mint mark; the Denver Mint succeeded an earlier federal assay office established during Colorado's gold rush era. The facility is a major U.S. coin producer and is part of the federal government's minting operations.
