Gilt 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 of domed form, just under 1 5/8” diameter. The edged pierced for the cross pin seat. The surface textured and worn from burial. Professionally refurbished with the 24karat gold overlay restored, on an 18” gilt Sterling silver neck chain for contemporary wear. Jewelry gift boxed with a certificate of authenticity. Fine proud form.
