A United States Note, also known as a Legal Tender Note, is a type of paper money that was issued from 1862 to 1971 in the U.S. Having been current for over 100 years, they were issued for longer than any other form of U.S. paper money. They were known popularly as "greenbacks" in their heyday, a name inherited from the Demand Notes that they replaced in 1862. Often called Legal Tender Notes, they were called United States Notes by the First Legal Tender Act, which authorized them as a form of fiat currency.
