| Obverse description | Central square hole (穿) surrounded by four Chinese seal-script characters reading 建炎通寶 (Jianyan Tongbao), arranged in a cruciform reading pattern — top, right, bottom, left — within a plain inner border. The characters are boldly cast in archaic seal script (篆書), exhibiting rounded, regular strokes characteristic of Song dynasty numismatic art. A raised inner rim frames the central perforation, while a plain outer rim defines the coin's periphery. The flat field displays a mottled dark green patina consistent with long burial, with minor surface porosity typical of period cast bronze. The overall fabric is well-struck with clear legend definition. |

| Reverse description | Plain reverse featuring a central square hole (穿) framed by a raised inner border, with a broad, flat, unadorned field extending to a plain outer rim. No legend, marks, or decorative elements are present. The surface exhibits a consistent dark green cuprite and malachite patina with areas of earthen encrustation, typical of Song dynasty cast bronze coinage recovered from archaeological contexts. The rim is moderately raised and well-defined, consistent with production from a carefully prepared clay mold. |
