Here's a bit of "money trivia" for you:
Soon, U.S. currency will be printed on sheets of 50 notes instead of the current 32 notes. The money will still look the same with the exception of some "fine print" meaning a couple of digits on the face of the bill that indicate where on the sheet the bill was located. Who knew they had this stuff?
