3 Cash - Dayi Tongbao

Chen Youliang proclaimed the Great Han dynasty in 1360 after murdering his own superior, Xu Shouhui, and declared himself emperor at Jiujiang. His regime lasted barely three years before Zhu Yuanzhang — who would found the Ming dynasty — destroyed his fleet at the decisive Battle of Lake Poyang in 1363, one of the largest naval engagements in history. The Dayi Tongbao coinage belongs entirely to those few years of contested rule.

Hartill notes the series is scarce relative to contemporaneous rebel issues, likely a product of Chen's limited territorial control and the disruption of bronze supply during constant military campaigning.
