The Mint was created by Congress with the Coinage Act this date in 1792. Per the terms of the Coinage Act, the first Mint building was in Philadelphia, then the capital of the United States; it was the first building of the Republic raised under the Constitution. Today, the Mint’s headquarters (a non-coin-producing facility) are in Washington, D.C. It operates mint facilities in Philadelphia, Denver and San Francisco and West Point, New York and a bullion depository at Fort Knox, Kentucky.
Originally part of the State Department, the Mint was made an independent agency in 1799. Under the Coinage Act of 1873, the Mint became part of the Department of the Treasury. It was placed under the auspices of the Treasurer of the United States in 1981. (from Wikipedia)
