| Reverse description | Plain ridged oval field with horizontal line texture across the entire surface, mirroring the obverse treatment. At the upper center, a faint raised rectangular impression is visible, the result of the obverse cartouche stamp pressing through the flan. A prominent circular seal stamp is applied at center, bearing the cursive monogram of the Goto assay house in grass script. Below and to the lower right, a smaller circular hallmark stamp bearing the Goto family authentication seal is impressed into the field, confirming the purity and weight of the piece. The reverse is characteristically plainer than the obverse, with stampings serving as quality and assay guarantees. |
