Looking for someplace where I can purchase various foreign country bills for an effect that bill changes from various countries several times to final of American bills. All I can find is prop money for US currency. I know money exchanges at airports can do some countries but the nearest one to me is 70 miles away, driving thru Detroit, no thanks! I would go to bank but live on border of US and Canada and tried that once and all they had were US and Canadian.

Ebay is the answer

Search "currency paper money foreign"
