What are the denominations of Federal Reserve Notes?

The US currently issues 7 denominations of Federal Reserve Notes: $1, $2, $5, $10, $20, $50, and $100.

At one time there were also Federal Reserve Notes with denominations of $500, $1000, $5000, and $10,000. $500 bills saw moderate use by businesses in the days before electronic funds transfers and widespread use of checks while the rest were very infrequently used. Production was discontinued in 1945, although the final printings carried a 1934 series date.

Banks were still allowed to distribute the bills on request, but they became popular as a way for criminals to easily hide large amounts of money without detection. That led the government to halt all distribution of high-value bills as of mid-1969.
