The first San Francisco Mint was open from 1854 to 1874 at 608 Commercial Street near Montgomery Street. The building was previously used by Moffat & Company, a private mint and assay office. The building became a Subtreasury (government office for holding bullion), then was a branch of the Bank of Canton, and now is the Pacific Heritage Museum with exhibits devoted to Asian art. There is a small mint museum in the basement of the building with some replica ore carts and bags.
