| Reverse description | Plain and uninscribed reverse, presenting a flat, featureless field surrounding the central square perforation. A modest raised inner rim borders the square hole, and a plain outer rim defines the edge of the flan. The surface exhibits a coarse, granular texture resulting from the sand-casting production method, overlaid with a dark grey-green patina acquired through prolonged burial or circulation. No mint marks, symbols, or secondary legends are present, which is consistent with standard Goryeo cash coinage of this type as catalogued under Hartill 25.72. |

| Additional information |
The Hae Dong Chung Bo was introduced in 1102–1103 under King Sukjong, part of a deliberate state effort to shift Korea away from its grain-and-cloth barter economy toward metal coinage — a project that had already failed once under Seongjong a century earlier. Sukjong established a dedicated mint office, the Jujeon Dogam, specifically to drive the transition. The public resisted anyway, and within decades coin use had again retreated to the margins of daily commerce.
