Quality control measures were implemented in that from each separate mass of gold or silver used to produce coins, three coins were set aside by the treasurer. Each year on the last Monday in July, under the inspection of the Chief Justice, the Secretary and Comptroller of the Treasury, the Secretary of State, and the Attorney General, the coins were to be assayed and if the coins did not meet established standards, the officers were disqualified from office. The meetings later became formalized as the United States Assay Commission, which continued meeting until it was disbanded in 1980.
