Gilt bronze, slightly over 7/8” diameter of rounded form with sharp edge, half rounded face and flat back. Worn in numbers on the surface of the jerkin, these metal brooches provided a measure of protection against sword cuts and, in fact, were a form of armor. See current Public Television programming for documentation of these in action. As protectors, they also held spiritual significance for the warrior. Some wear from use and surface textured from burial. Professionally conserved and the gold surface restored. On a modern premium black leather neck cord. Gift boxed with certificate of authenticity. Good representative example.
