  • Pieces with ???BRONZE??? stamped on the edge may have been so marked to clearly distinguish them from medals of the same design that were also struck in other metals such as silver or gold or if some bronze pieces were later plated in precious metal ??? and subsequently marked ???PLATED.??? If the job was only struck in bronze and never plated, the metal name may not have been applied to the edge
