1 Unit

Maingmaw was one of several Pyu city-states in the Irrawaddy basin that developed sophisticated urban economies well before Burman migration reshaped the region. These silver units — often called "rising sun" coins in the literature — circulated within a trade network connecting the Bay of Bengal ports to inland agricultural centers. The specific weight standard used at Maingmaw shows influence from Indian ratti-based systems, suggesting direct commercial contact with South Asian merchants rather than purely inland exchange.
