Can you name all of the denominations of U.S. currency that have ever been used?
Only includes circulating currency. Examples of excluded currency include the $50 Colombian Expedition coin, and the $100 Platinum Eagles.
Years of issue only count for those that produce the coin in business strike for intent to circulate, so Sacagawea coins would count, but NIFC half dollars wouldn't.
Banknotes used exclusively by the federal reserve and other banks (i.e. $10,000) are not included.
These were used for trade between banks that needed to exchange large amounts of money and weren't really in public circulation.
