This pin is a real charmer! It is not marked but tests positive for silver. I just love the high relief cherub as well as the cartouch which thankfully has no initials. The pin is 2 5/8 inches long by a tad over 1/2 inch wide. It has gold gilding on the back and its original iron pin back with t bar hinge and c catch. C. 1880 and in very good condition.
