| Obverse description | Plain hammered gold oval field bearing a vertical ink-brushed inscription in cursive Japanese calligraphy (sumikaki), applied in black ink directly onto the gold surface. The central column reads '京目壹两駿河' (Kyō-me Ichi-ryō Suruga), denoting the Kyō-me weight standard of one ryō issued in Suruga province. A smaller secondary inscription appears to the right of the main column, likely an assayer's or official's notation. At the lower portion of the field, a raised oval seal impression is visible, characteristic of Tokugawa-period koban authentication marks. The granular, textured surface reflects the characteristic ishime (stone-ground) finish of early Edo-period koban coinage. |
