| 正面描述 | Cast bronze cash coin featuring a central square perforation surrounded by a raised inner rim. Four Chinese characters in regular script (kaishu) are disposed in cruciform arrangement around the central hole, reading clockwise from top: 天 (tiān), 盛 (shèng), 元 (yuán), 寶 (bǎo), forming the reign-era legend 'Tiansheng Yuanbao'. The characters are boldly rendered in raised relief with well-defined strokes. A raised outer rim borders the coin, and the flat field between the inner and outer rims shows the characteristic granular surface typical of sand-cast production. Patina is dark olive-brown with traces of green cuprite. |

| 背面描述 | Plain reverse with a central square perforation framed by a raised inner rim and a raised outer rim. The broad intervening field is entirely blank and unadorned, displaying a smooth to slightly granular cast surface consistent with the standard reverse treatment of Western Xia cash coinage. The surface shows an even dark brown patina with scattered patches of green oxidation, typical of buried bronze from this period. |

The Western Xia — the Tangut state occupying the Ordos and Gansu corridor — maintained its own coinage tradition largely independent of Song Chinese influence, though the Tiansheng Yuanbao series shows clear calligraphic borrowings from contemporary Song cash. Tiansheng was the reign title of Renzong, the longest-reigning Western Xia emperor, whose 54-year rule accounts for much of the dynasty's numismatic output. The state was conducting a three-way balancing act between Song, Jin, and later the rising Mongol threat throughout this period.
Hartill notes that Western Xia bronzes are frequently found in poor alloy, contributing to the surface granularity common across the type.
