United States one-dollar bill
The United States one-dollar bill (US$1), sometimes referred to as a single, has been the lowest value denomination of United States paper currency since the discontinuation of U.S. fractional currency notes in 1876. An image of the first U.S. president (1789–1797), George Washington, based on the Athenaeum Portrait, a 1796 painting by Gilbert Stuart, is currently featured on the obverse, and the Great Seal of the United States is featured on the reverse. The one-dollar bill has the oldest overall design of all U.S. currency currently being produced. The reverse design of the present dollar debuted in 1935, and the obverse in 1963 when it was first issued as a Federal Reserve Note.

The United States dollar is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.
