1 Mu - Mindon Min

Mindon Min introduced a standardized coinage system for Burma in 1853 — the first in the kingdom's history to be struck by machinery rather than cast or hand-hammered. The reform was partly a response to pressure from British India following the Second Anglo-Burmese War, which had just stripped the Konbaung Dynasty of the entire southern coastline. Mindon, newly on the throne, needed to consolidate economic administration in what remained of his kingdom.

The mu was the smallest silver denomination in the new series, denominated within a traditional Burmese weight system rooted in the kyat.
