The artist I mentioned in class is J.S.G. Boggs. He draws, or finishes drawing, his currency in public places, waits for a crowd to gather and someone to say something along the lines of 'gee, that's quite a drawing you have there' before asking if they will accept it for the equal amount of goods. His work is one-sided and usually only of low denominations - the stated idea of the performance being to see whether or not someone will accept art instead of money.
