Regarding American money.

Ok, currency primer. There are 100 cents in a dollar. A penny is worth one cent, a nickel is worth 5 cents, a dime is worth 10 cents, a quarter is worth 25 cents. We do have half dollars (50 cents) and silver dollars, but these are rare. Then we have 1 dollar bills, 5 dollar bills, 10 dollar bills, 20 dollar bills, 50 dollar bills and 100 dollar bills. Hope this helps.
