This is a 1940's to 1950's era set of regal crowns.  The pin is an unusual set of three pins, all of the same size and attached to the center pin by a chain.  All of the pins have their own safety clasp closure and all of the crowns are marked "STERLING" on the back.  The earrings are screw-backs with the word Sterling stamped on the post as well.  A delightful treasure, each crown measu7res 15/16" wide and 1/2" tall.
