| Reverse description | Plain reverse field with a raised inner square rim surrounding the central square perforation and a raised outer rim at the coin's periphery, both typical of Northern Song Dynasty cast cash coinage. The field between the inner and outer rims is devoid of any inscription, mint mark, or decorative device. The surface presents a dark brown patina with areas of olive and green oxidation consistent with prolonged burial or circulation. The casting quality is consistent with standard Song government mint production. |

| Additional information |
Tiansheng Yuanbao was issued under Emperor Renzong, who ascended the throne as a child of twelve in 1022 under the regency of Empress Dowager Liu — one of the most capable administrators of the dynasty. The cash series bearing this reign title ran through 1031, produced across multiple northern mints during a period of relative fiscal stability before the costly frontier conflicts with the Xi Xia would later strain Song bronze reserves.
The regular script variety catalogued by Hartill as 16.76 is the more commonly encountered of the two script types for this issue, the seal script counterpart being considerably scarcer.
