1 Cash - Tiansheng Yuanbao, Regular script

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.
