These coins, with the French (or similar) coat of arms on one side, were made by numerous Italian states in the mid-1600s for use in trade with the Ottoman Empire. In Italian they are known as "luigini", as they are indeed imitations of coins of Louis XIV. I own one luigino, similar to
this one, from the otherwise numismatically unremarkable state of Loano.
This one is more a copy-of-a-copy, as the coin was clearly made by an amateur - they didn't even know they were supposed to carve the dies "backwards". The backwards "666" visible above the crown is presumably an attempt at reproducing a "1666" date. Given its crudeness, it wasn't made to fool modern collectors, so I'd assume it does actually date from the mid-1600s - and was probably made locally in Greece, Turkey or Egypt rather than France or Italy.
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
