Sterling Silver Enamel Charm - St Louis Cardinals | Baseball Playing Cardinal

Dating to the 1980s or so, may I offer this Sterling Silver (hallmarked as pictured) and enamel charm - a souvenir from a visit to a baseball game. Depicting a St Louis Red Cardinal, the charm shows the bird at bat. The back of the charm does bear the initials IC - I don't know if that is a maker mark but it seems more that than the initials of a person (its too small). Add a jump ring (or remind me and I will add one) and its ready for a charm bracelet! Size/Weight: 1-1/8" high (to top of bale) x 9/16" wide. Weight is 1.6 grams. Very fine condition with no problems I can spot.
