A while back 4 of these same 16mm antique buttons sold on a well established auction for $79 and a pair of ears (they took off the shanks, shame on them) for around $90. Here you should see the teensie tiny 8 pear shape rivets spoking out from the 2mm center rivet. The filigree frame looks to have a gold wash on it, metal loop shanks intact. New ear hooks sterling and one is stamped so.
