A jeton would be my guess, but I can't quite make out the inscription. It looks like "GETTOS BICH PANES..." - "GETTOS" I would assume being jeton, or token, and "PANES" being Latin for bread. Unfortunately, Google is insisting on re-interpreting my search for that phrase as "ghettoes beach planes" and wants to show me pictures of aircraft landing on St Martin, so not much help there, I'm afraid.
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
