| Obverse description | Cast bronze cash coin centred by a raised-rim square perforation, around which four Chinese characters in kaishu (regular script) are disposed in clockwise reading order, one character in each quadrant of the field: 開 (top), 禧 (right), 通 (bottom), 寶 (left), together forming the reign-title legend 開禧通寶 (Kaixi Tongbao). The characters are rendered in bold, well-defined strokes with a raised inner square rim framing the central aperture and a raised outer rim encircling the coin. The field surface shows the characteristic granular texture of sand-cast production. |

| Reverse description | The reverse is entirely plain and uninscribed, presenting a flat, featureless field retaining its original sand-cast surface texture, now covered with an even patina of brown and olive-green corrosion products. The raised inner square rim surrounding the central square perforation and the raised outer rim are both visible, consistent with standard Southern Song dynasty cash coin production. No mint marks, symbols, or supplementary inscriptions are present. |
