Silvered bronze, worn in numbers on the surface of the jerkin, to provide 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.  Circular, just over 7/8” (0.91”) diameter. The surface textured and worn from burial. Professionally refurbished with the silver overlay restored, on an 18” sterling silver neck chain for contemporary wear. Jewelry gift boxed with a certificate of authenticity. Fine proud form.
