Just under 1” diameter, circular, with cylindrical center and the front face curving from the center. The reverse flat. Worn in numbers on the surface of the jerkin, these small metal brooches provided a measure of protection against sword cuts and, in fact, were a form of armor. As protectors, they also held spiritual significance for the warrior. See current Public Television programming for documentation of these in action. Surface textured from burial and professionally refurbished with the gold overlay restored, on leather neck cord for contemporary wear. Gift boxed with a certificate of authenticity. Large size.
