10 Cash Tianguo / Shengbao

The Taiping Heavenly Kingdom was a millenarian Christian theocracy that controlled much of southern China between 1851 and 1864, killing an estimated 20–30 million people in the process — making the Taiping Rebellion one of the deadliest conflicts in human history. These coins were struck at Nanjing after Hong Xiuquan's forces captured it in March 1853 and renamed it Tianjing, their heavenly capital. The "Tianguo" inscription marks this as currency of that state, not Qing imperial coinage.

Production was short-lived. By 1855 the Taiping mint had effectively ceased functioning amid internal power struggles and military pressure from Qing forces and foreign-backed armies.
