1 Cash - Jiayou Yuanbao, Clerical script

Cast during the reign of Emperor Renzong under the Jiayou era name (1056–1063), this cash belongs to a period of Song fiscal conservatism that saw relatively controlled bronze output compared to the inflationary casting runs of later Northern Song reigns. Renzong's court was unusually stable — his reign of over forty years remains the longest of any Song emperor — and the Jiayou era coinages reflect that administrative steadiness in their generally consistent module and casting quality.

The clerical script variant catalogued here as Hartill 16.148 is the more commonly encountered of the Jiayou types, the seal script version being considerably scarcer.
