The United States Mint has minted numerous commemorative coins to commemorate persons, places, events, and institutions since 1848. Many of these coins are not intended for general circulation, but are still legal tender. The mint also produces commemorative medals, which are similar to coins but do not have a face value, and therefore are not legal tender.

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 U.S. Mint is one of two U.S. agencies that produce money in the case of minting coinage; the other is the Bureau of Engraving and Printing, which prints paper currency. The first United States 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.
