| Obverse description | Central square perforation surrounded by a raised rim. The four-character inscription 常平通寶 (Sangpyong T'ongbo) is arranged radially around the central hole, reading top to bottom and right to left in traditional Chinese regular script. 常平 (Sangpyong), referring to the Joseon dynasty's Ever-Normal Treasury (Sangpyong-cheong), appears at the top and bottom positions, while 通寶 (T'ongbo), meaning 'circulating currency', appears at the right and left positions respectively. The characters are rendered in clean, rectilinear strokes characteristic of cast Joseon cash coinage. |

| Reverse description | Central square perforation with a raised rim. The mint control mark 捻 (Chong), denoting the General Military Office (捻戎廳, Chongyungchong), appears at the top position above the hole. A series number in Chinese numerals is placed at the bottom position, indicating the specific casting series (e.g. 九 for series 9). A crescent mark appears to the right of the central perforation, serving as an additional foundry or batch identifier. The reverse field is otherwise plain, consistent with standard Joseon cast cash coinage practice. |
