1 Cash - Tiansheng Yuanbao, Regular script, iron

Tiansheng Yuanbao was issued under Emperor Renzong, who came to the throne as a boy of eleven in 1022. Iron cash of this reign were struck primarily to compensate for chronic copper shortages in the northern circuits, where Song authorities had long struggled to maintain adequate coin supply against the competing demands of military expenditure and trade with the Liao dynasty along the frontier. Iron coinage was actively discouraged from circulating outside designated regions — cross-border movement was a punishable offense — making survivors of this type geographically concentrated finds.
