Acquired these on eBay. They were described as Italian chips. The small printing on the top chip says, "Rekords Mod. Dep.---Fiche Da Gioco". The little lettering on the other chips is, "Jollymilano---Mod.Dep." They are very thin--about half as thick as a slot card. They also feel quite solid/strong plastic.
If anybody knows anything about these--would appreciate the info. Thanks. Doug
