10 Cash Xingchao Tongbao

The Kewang regime — a Southern Ming resistance government established by Zhu Youlang's ally Sun Kewang in Guizhou and Yunnan — minted the Xingchao Tongbao series as explicit political currency, asserting dynastic legitimacy against the consolidating Qing. Sun Kewang held effective control as a warlord king while nominally supporting the Yongli Emperor, a tension that collapsed entirely when he defected to the Qing in 1658, abruptly ending both his regime and this coinage.

The 10-cash denomination required the substantial brass flans that make survivors prone to casting porosity — a known issue with this type rather than a strike deficiency.
