Silvered bronze. Just under 7/8” diameter, of full robust form. Circular with rounded face and flat back forming a ridged edge. Inlet for the cross pin. When fastened to the jerkin, these small 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. Professionally refurbished with the silver overlay restored and suspended from a Sterling silver mounted 18” neck chain. Gift boxed with certificate of authenticity.
