The United States Mint is a bureau of the Department of the Treasury responsible for producing coinage for the United States to conduct its trade and commerce, as well as controlling the movement of bullion. The Mint was created in Philadelphia in 1792, and soon joined by other centers, whose coins were identified by their own mint marks. There are currently four active coin-producing mints: Philadelphia, Denver, San Francisco, and West Point.
The Mint's largest facility is the Philadelphia Mint. The current facility, which opened in 1969, is the fourth Philadelphia Mint. The first was built in 1792, when Philadelphia was still the U.S. capital, and began operation in 1793. Until 1980, coins minted at Philadelphia bore no mint mark, with the exceptions of the Susan B. Anthony dollar and the wartime Jefferson nickel. In 1980, the P mint mark was added to all U.S. coinage except the cent. Until 1968, the Philadelphia Mint was responsible for nearly all official proof coinage. Philadelphia is also the site of master die production for U.S. coinage, and the engraving and design departments of the Mint are also located there.
