1/4 Unit Halin

The Pyu city-states of upper Burma operated as commercially sophisticated polities well before Burman migrations reshaped the region, and Halin — the northernmost of the major Pyu centers — issued coinage tied to a weight standard traceable to early Indian reckoning. The quarter-unit designation places this piece within a fractional system designed for small-scale market exchange, not tribute or ceremonial use. Halin fell into decline sometime after the 9th century, likely accelerated by Nanzhao raids from Yunnan documented in Tang Chinese sources around 832 AD.
