Euros. Euros is not in the US because it is the currency for most European countries.
It is the rest because:
$50 dollar bills: There is a US 50 dollar bill, which has our 18th US president Ulysses S. Grant on there.
Dollar coins: The older the better.... there was a act passed in the US that enabled valuable material such as gold or silver to be placed on the coins, leading to immense costs.
Checking account deposits: Literally, if we don't have these, we don't have banks, and if we don't have banks, every other day someone is going to be digging a hole in their backyard to bury their savings.
hope this helps
