3 Cash - Jiading Yongbao, Ding, with value, iron

Copper had been critically short in the south since the Jin conquest stripped the dynasty of its northern mints and resource base. Iron coinage expanded aggressively to fill the gap, and the Ding furnace mark on this piece identifies the specific casting facility responsible for production, a bureaucratic detail that became increasingly important as quality control across multiple foundries deteriorated.
