A Perfect Counterfeit

A man can make perfect counterfeit bills. They look exactly like real ones, they’re made of exactly the same materials, made the same way, everything. So perfect, one could pretty much call them real bills. One day he successfully makes a perfect copy of another bill. However, he gets caught when he tries to use the copy. How is this possible?

As a counterfeiter, he had lots of counterfeit bills around and he accidentally used one of them as his original. So he made a perfect copy of a counterfeit bill.

An exact copy would not have a discrete serial number. This is a case where duplication can be too perfect.

The serial number would be absent, duplicated, or not exist within the US database. Granted it would probably take a lot more time and more than one attempt to catch him than the question implies, he would inevitably get caught if he made lots of them and tried to use them for large purchases. He could get away with making singles or fives and getting free food to save his money for other things since by the time anyone would notice these to be fakes, they would have probably circulated hundreds of times.
