Copper, just under 1 3/4” diameter. Broad band with lattice borders, raised with eight hemispherical projections, each with stipple bass border, to engage the blade of an attacker. Original cross pin. Glossy brown patina over light wear from its time of use. Worn in multiples attached to leather or heavy wool jerkins, this example is easily capable of absorbing a sword blow without failure. Large iconic representative of these protective dress accessories.
