Countries with the US dollar

Divisions and denominations

1 U.S. dollar is equivalent to 4 quarters, 10 dimes, 20 nickels, 100 cents or even 1,000 mill. The $1 piece is also colloquially known as a "buck," and the $10 bill as an eagle. While these terms are quite common within the U.S., the terms of the dime, nickel and eagle have never been officially established. Calling the dollar a "greenback" dates back to the time of the first bills around 1861, when it was given the distinctive green color.

The largest existing bill bears the portrait of Woodrow Wilson and has a value of 100,000 USD. Even though it is still legal tender today, it was never in circulation, but was merely exchanged between central banks starting in 1934. The largest banknote still printed today is the $100 bill. All bills with higher denominations were withdrawn by the Federal Reserve Bank in 1945.
