Copper-alloy, 4.31 grams, 21.26 mm. Circa 6th-7th century AD. A short-lived fashion was for Anglo-Saxon shield-bosses to be surmounted by a short shank and flat decorative disc mount. The central field is surrounded by three ridges, with traces of beading. Much of the gilding is still present. Reference: Dickinson, T. & Härke, H. Early Anglo-Saxon Shields, Society of Antiquaries, London, 1992. Very fine condition.
