Pennylicious has some very good examples of different, and fun money. My favorites below:
Completely legal tender, the 10,000 bill was made from 1945-1969, and let me tell you this, looks weird.
Though unofficial, i would still get one, when i go to Antarctica.
Completely awesome, mostly hand drawn, although some computer made ones, J.S.G. Boggs has created some awesome money. And it’s legal to accept it too.
