| Reverse description | The reverse presents a plain, unadorned field enclosed by a beaded inner border running the full circumference. At center, the two-character Japanese inscription 試作 (shisaku, meaning 'prototype' or 'trial piece') is incused in bold strokes, confirming the experimental nature of the piece. The simplicity of the reverse is characteristic of pattern and trial coin production at the Japan Mint, where the reverse was often left largely blank to focus evaluation on the obverse design. |
