100 Cash - Shuntian Yuanbao, with crescent and dots

The Great Yan State was the rebel polity carved out by Shi Siming after he recaptured Luoyang from Tang forces in 759, effectively reigniting the An-Lushan Rebellion following his murder of An Qingxu. The Shuntian Yuanbao coinage was his imperial currency, issued as Shi Siming declared himself Emperor of Yan — a direct repudiation of Tang legitimacy. The crescent and dot varieties represent die-position control marks, a practice borrowed from Tang minting administration and turned against it.

Shi Siming was killed by his own son, Shi Chaoyi, in 761, collapsing the issuing authority mid-production.
