1 Gold unit - Sudhammapura

Sudhammapura was the Mon name for Thaton, a port city in lower Burma that served as a major node in the maritime trade network connecting the Bay of Bengal to mainland Southeast Asia. Gold coinage of this type circulated alongside Indian, Gupta-influenced, and Pyu issues — the weight standard of roughly 6.4 grams aligns loosely with fractions of the Indian suvarna, suggesting the Mon were calibrating to regional mercantile norms rather than asserting an independent metrological system.

Thaton was sacked by the Pagan king Anawrahta in 1057, an event that effectively ended the Mon kingdom's political independence and dispersed much of its court culture northward.
