1 Cash - Dasong Yuanbao, Han, iron

Dasong Yuanbao iron cash were struck during the reign of Emperor Lizong, who ascended the Southern Song throne in 1224 under the regency of Shi Miyuan. Iron coinage at this period was a fiscal stopgap — copper supplies were chronically diverted toward bronze weaponry and the bribes paid to Jin dynasty border commanders, leaving the Southern Song treasury reliant on cheaper metal for everyday transactions. Hartill 17.685 places this type firmly within that constrained monetary environment.
