Yes. I don't think we've ever nailed down exactly where these things came from, but they're a very common brass replica of a late mediaeval Spanish silver coin. But we see people posting them on the forums so often, they must have been mass-produced, so I can only assume it was some kind of mass-marketing gimmick, by Readers Digest or similar.
The Latin legends are all garbled and unreadable, but the design is based on the silver real of Ferdinand and Isabella, circa AD 1500. Given that timline, my assumption on the Readers Digest theory is they used it to promote a book on Christopher Columbus.
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
