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. 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. These notes almost became money. The difference between a United States Note and a Federal Reserve Note is that a United States Note represented a "bill of credit" and was inserted by the Treasury directly into circulation free of interest. Federal Reserve notes are legal tender currency notes.
