10 Cash - Taihe Zhongbao, Seal script, larger size

The Taihe reign (1201–1208) of Emperor Zhangzong saw the Jin dynasty struggling to finance military commitments against both the Southern Song and the Mongol confederacies forming to the north. Large-denomination cast bronzes like this ten-cash piece were part of a broader inflationary monetary policy — issuing high-face-value coins to stretch a shrinking metal supply. The larger module of this variety distinguishes it from the standard Taihe ten-cash issues catalogued under the same reign, a size differential that likely reflects a separate casting run rather than a simple production variation.
