American paper currency comes in seven denominations: $1, $2, $5, $10, $20, $50, and $100. The United States no longer issues bills in larger denominations, such as $500, $1,000, $5,000, and $10,000 bills. But they are still legal tender and may still be in circulation.

Most circulated Federal Reserve Notes from more modern series are worth no more than face value. Some of the early series notes (1928 and 1934) do carry a small premium, although for circulated notes this premium is small, usually 10% to 30%.
