German play-money manufacturers often made quite realistic-looking replica coins (including dates, mintamrks, etc), only they were in miniature. I believe German law at the time allowed for it, as long as the toy money was significantly smaller than genuine coins.
Such "toy coins" would of course not be legal anywhere today, as they would be considered a choking hazard.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
