Copper-alloy, 4.69 grams, 18.02 mm. 13th-16th century AD. A cast rectangular plate with two extensions on the upper edge forming the loops of a simple hinge or folded buckle plate (lost in antiquity). The border runs around the central recess, and is indented to accommodate the two rivet holes in the lower corners. The reserved design is in the form of an advancing wyvern, his two front limbs placed close to the border and his broad tail lashing out behind, giving his body an s-profile.
