FOREIGNER Logo vintage crystal/enameled badge (green background). The 2 circles under the band's name are probably a wink to 4's cover film leader.
It comes from an early 80s private collection (probably 1980/1981).
It's in a very good condition, as per pictures. The back bears the engraved mention "MADE IN ENGLAND" on a brass-plated (?) metal base.
