During a time travel adventure in season 3 of Enterprise, Archer and T'Pol convinced an ATM that it needed to hand over a lot of notes. And I'm pretty sure the time Voyager ended up in the 90s, they just told the Replicator to magic them up some money, because of course they happened to have that on file.

This leads to the mental image of them all having the same serial number, and Janeway getting busted for counterfeiting.
