Reverse description Entirely blank concave field, devoid of any design, inscription, or decorative element. The surface exhibits concentric circular tooling marks consistent with lathe work on the die preparation, and the lead flan retains an irregular, roughly squared perimeter with pronounced concavity, confirming this piece's status as a reverse trial used solely to evaluate the obverse die.
