Thai Binh Thanh Bao ("Sacred currency of Thai Binh") / Blank. 21mm, 1.56 grams. Toda #166; Barker 54.1-54.3

Cam-giang Vuong was the brother of a successful military leader Le-Uinh, who rebelled against the Emperor, and led a short-lived and unsuccessful rebellion in 1509. 

At various times many rebel leaders proclaimed themselves as Lords, Kings, and Emperors, and had produced their own coinage with their reign names and titles on them, but as their rebellions would prove unsuccessful or brief, their reigns and titles would go unrecorded in Vietnamese history, so the coins produced by their rebellions cannot easily be classified.
