Coat of Arms Charles X Roi de France Pin Brooch, Antique Coro Pewter Crown

Very rare coat of arms with Charles X Roi de France portrait pin brooch. I think it is pewter made. The brooch is in nice vintage condition, I found couple of dents on the edges of the round coin portrait and the clasp is not fasten to brooch, it is sliding back and forth. Would be glued. Signed Coro. Size ~ 3.5 cm x 2.9 cm Weight ~ 12 g
