The Coinage Act of 1792 established the United States dollar on equal footing with the Spanish silver dollar, splitted it into 100 cents, and authorised the minting of coins in dollars and cents. Federal Reserve Notes, popularly known as dollar bills due to their primarily green colour, are the currency of the United States.
