Some questions about American counterfeit currency - How big a problem is it? How much cash in circulation is counterfeit? How good is a well made fake? Can it fool banks? How much do they typically sell fake notes for?
I’ve heard that the majority of counterfeit American currency is in foreign countries. In several countries, US dollars are used as a de facto currency, with the twenty dollar bill being the main denomination. I’ve read that in some areas as much as 25% of these twenties are counterfeit.
