1 Cash - Tianding Tongbao

The Tianwan Kingdom lasted barely two years. Chen Youliang declared it in 1359 after murdering Xu Shouhui, the leader of the Red Turban rebel movement whose forces he had effectively controlled for years — an act of internal treachery that consolidated his power but cost him broader rebel legitimacy. His subsequent war against Zhu Yuanzhang, the future Hongwu Emperor, ended decisively at the Battle of Lake Poyang in 1363, one of the largest naval engagements in history. Chen died during that battle, and the Tianwan state collapsed with him, making this cash issue one of the shortest-lived coinages of the entire Yuan-Ming transition period.
