Plain-rim, machine-engraved circular plate featuring the coat of arms of Prussia, consisting of a crowned, spreadwing, shield-body eagle bearing Frederick the Great's "FR" monogram and grasping an orb and scepter in its talons. Rim face is decorated in four segments, each with a semicircular, petaled motif against a textured ground; no foot ring. Underside is engraved "N.B." and "Tieling (four-dot diamond)" with "T" scratched to its right on rim, and struck with two touch marks at center of well, the raised serif letters "SP" and "HSS" across a combined figure of an anchor becoming a "4" and "+" at its top, both in shaped shields.
