The United States $100 bill is known the world over. According to former Federal Reserve Chairman Ben Bernanke, two-thirds of all $100 bills circulate outside of the country. The United States also printed $500, $1,000, $5,000, and $10,000 bills until the 1940s. In 1969, denominations of US currency over $100 were declared obsolete by executive order of President Nixon, and there are no plans to resume their printing, partly for concerns of their use in organized crime.
