I saw a documentary on casinos, and he was mentioned in one of the programs. I don't kow if it was him or one of the others, but someone produced slot machine tokens the casino couldn't tell from the ones they had had made.
Same thing caught their eyes, too many of them were in the system. The documentary pointed out that if he hadn't gotten gready, say only made less than 10, he likely would never have been caught.
if hed had only made 10-20, hed likely not have made back the costs of the counterfeiting.
and that is, in short, the point of a lot of anti-counterfeiting measures. it's not that they
cant be duplicated (after all, the mint is pumping out millions of these things), but that the
costs of doing so is so high its not worth the effort. this is why most counterfeiter tend to fake larger denominations of notes, because it costs as much to fake a £5 note as a £50 note, but the payoff if its accepted is ten times as big.
the Mint itself isn't bothered about those high costs, as it can A) print in bulk in a way that counterfeiters just simply cant (like I said, millions of notes),and B) isn't trying to make a profit as its state-funded.
On topic, I take the view that the lack of secondary currencies in Traveller is, in part, a game mechanics abstraction, in that the
characters might have a mix of notes issued on Mora, Regnia, some Zhodani notes (just in case) and a half dozen other worlds in their regular haunts, but the
Players, being here for a game, are not intrested in the minutiae of the conversion rates of Mora credits to whatever the locals on this world use, so we treat it all the same as "Imperial Credits", so that they can get a really quick and easy answer to the questions "how much?" and "can we afford it?"
