I don't know how relevant it is, but the "Doty Encyclopedic Dictoionary of Numismatics" uses, as their primary example of mules, the various issues of Mexican coins from the Alamos mint in the 1870's. Doty doesn't explicitly say so, but they could well be the first coins called "mules", though "muling" of tokens was known about as far back as the 1790's.
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
