| Additional information |
Jiayou was the final reign period of Emperor Renzong of Song, who ruled for over four decades — the longest reign of any Song emperor. By the 1050s, the Northern Song mint system was under considerable administrative strain, producing cash coins across dozens of furnaces at multiple provincial locations simultaneously. The Jiayou yuanbao series was cast in both regular and seal script varieties as a deliberate aesthetic choice, not a minting accident, reflecting a court fashion for calligraphic variation on coinage that peaked under Renzong's patronage of the arts.
Hartill 16.146 is among the more frequently encountered Jiayou types, though provincial casting quality varies considerably across surviving examples.
