2 Mun Hun

The Hullyondogam — the Military Training Command established in 1593 in the immediate aftermath of the Japanese invasions — was one of several government offices granted minting authority in Joseon-era Korea as a revenue mechanism rather than out of any centralized monetary policy. Each office struck its own cash coins, distinguished by reverse mint marks, and the resulting proliferation of issuers created chronic problems with quality control and weight standardization throughout the eighteenth century. The 1752 date places this piece within the reign of Yeongjo, who made repeated attempts to rationalize copper coinage circulation during his exceptionally long rule.
