| Reverse description | Plain field surrounding the central square hole, with a single Chinese character 黃 (Hwang) positioned above the perforation, identifying the issuing mint as the Hwanghae Provincial Office (黃海監營, Hwanghae Kamyong). The reverse follows the standard Joseon cash coin format, with the mint identifier as the primary device. The character is rendered in regular script within a plain circular border. |

| Additional information |
The 1 Mun cash coinage of Joseon was produced by multiple government bureaus and military offices simultaneously, each adding their own mint mark to the reverse — a system that makes attribution complex and renders some issuing offices dramatically rarer than others. KM#910 corresponds to a specific bureau issue within that sprawling administrative network.
By 1742, the Joseon court had been struggling for decades to maintain copper supply, partly due to limited domestic ore and ongoing competition from Japanese copper markets. Counterfeiting was chronic enough that royal edicts addressing it were issued repeatedly throughout the mid-18th century.
