title: Banknotes of the United States dollar
context: They were first issued in 1914, different from the Federal Reserve Bank Notes in that they were liabilities of the whole Federal Reserve System. They were redeemable in gold until 1933. After that date they stopped to be redeemable in anything, much like United States Notes (which later led to the halting of the production of United States Notes). They switched to small size in 1929 and are the only type of currency in circulation today in the United States. They were originally printed in denominations of $5, $10, $20, $50, $100, $500, $1,000, $5,000 and $10,000. The $500, $1,000, $5,000 and $10,000 denominations were last printed in 1945 and discontinued in 1969, making the $100 bill the largest denomination banknote in circulation. A $1 note was added in 1963 to replace the $1 Silver Certificate after that type of currency had been discontinued. Since United States Notes were discontinued in 1971, Federal Reserve Notes are the only type of currency circulating in the US. In 1976, a $2 note was added, 10 years after the $2 denomination of United States Note was officially discontinued. The denomination proved to be unpopular and is now treated as a curiosity, although it is still being printed. Starting 1996, all notes except $1 and $2 were redesigned to have a larger portrait of the people depicted on them. Since 2004, all notes (except $1 and $2) were progressively changed to have different colors to make them more easily distinguishable from each other, until the last such note was introduced in 2013 (the $100).
