The Secretary of the Treasury shall carry out duties and powers related to refining and assaying bullion, minting coins, striking medals, and numismatic items at the mints. However, until the Secretary decides that the mints are adequate for minting and striking an ample supply of coins and medals, the Secretary may use any facility of the United States Mint to mint coins and strike medals and to store coins and medals.

Laws on mints, officers and employees of mints, and punishment of offenses related to mints and minting coins apply to assay offices, as applicable.
