| 正面描述 | Cast copper coin featuring a central square perforation framed by a raised inner rim. Four Chinese characters are arranged in cruciform order around the central hole, reading clockwise from the top: 文 (top), 永 (right), 久 (bottom), 宝 (left), together forming the reign-era inscription 文久永宝 (Bunkyū Eihō, 'Eternal Currency of the Bunkyū Era'). The characters are rendered in a simplified, cursive style characteristic of this series, with 攵 used in place of the standard 文. The flat field between the characters and the outer rim is plain, and the overall design reflects the utilitarian cast aesthetics of late Edo period coinage. |

| 背面描述 | Cast copper reverse featuring a prominent decorative wave pattern (nami) radiating outward from the central square perforation toward the outer rim. The design consists of multiple overlapping scaled or fan-shaped wave segments arranged concentrically around the hole, a motif characteristic of the Bunkyū Eiho 4 Mon series and serving as the primary diagnostic field for distinguishing die varieties. The wave elements fill the entire reverse field between the inner rim of the square hole and the plain outer border, with no inscriptions present. Subtle differences in wave height, the position of wave 6 relative to the inner rim, and the dot placement on the character 永 on the obverse collectively identify the specific die variety. |
