1 Mun Ho

The 1 Mun was the workhorse coin of the Joseon Dynasty, cast rather than struck — a production method that persisted in Korea long after Chinese and Japanese mints had transitioned away from it. By 1806, dozens of authorized casting furnaces operated across the peninsula under the Bureau of the Military National Fund and other government offices, each adding a distinct reverse mintmark. KM#10 corresponds to a specific furnace attribution, though provenance among these issues is frequently muddled by the sheer volume of nearly identical types produced across overlapping years.
