The United States Mint was founded in 1792, and the Mint building in the then-national capital of Philadelphia was the first Federal building erected under the Constitution. In a gesture to emphasize its independence from Europe, the United States adopted its own currency using a decimal coin system.
Today, the Mint is a self-funded agency, and forwards an annual profit to the U.S. Treasury. The U.S. Mint produces all the circulating coinage of the United States, at an annual rate of between 11 billion and 20 billion coins. The U.S. Mint is also the sole provider of United States numismatic products: proof, uncirculated, and commemorative coins, and bullion coins minted from gold, silver, and platinum.
The most popular coins from the U.S. Mint are the gold and silver American Eagle series, and the 24k gold American Buffalo bullion coin.
