Hey, can you make change for this twenty dollar TRIVIA QUIZ??!!??

Today's trivia quiz is brought to you by the Community Currency Association. Hmm, each state creating its own currency...finally we can get away from this whole "united" states notion!

While we still have one national currency, what material are US dollar bills made out of? Please feel free to send me any bills that you examine to come up with the answer for this one ;)

Good luck!
