1 Mun Seal script

Historical Context: The 1 Mun Seal script coin, issued between 1097 and 1107, marks a pivotal period in Goryeo Dynasty monetary history, primarily under King Sukjong (r. 1095-1105). Sukjong initiated robust monetary reforms, aiming to establish a stable metallic currency system and reduce reliance on barter or foreign coinage. This issue was part of a broader effort to modernize the Goryeo economy and assert national sovereignty through a standardized circulating medium, reflecting progressive economic policy.

Artistry: The coin's design prominently features characters rendered in Seal script (전서, jeonseo), a classical calligraphic style. While specific engravers are unrecorded, the choice of Seal script signifies a deliberate embrace of formal, dignified aesthetics, aligning with scholarly and official traditions. This stylistic decision imbued the coinage with authority and antiquity, connecting it to revered cultural forms. The standard round shape with a square central hole, ubiquitous in East Asian coinage, symbolizes the harmony of heaven and earth.

Technical/Grading: As a cast bronze coin, 21.2 mm in diameter, its technical quality depends on mold integrity and foundry skill. High-points for evaluation include the sharpness and completeness of the Seal script characters, which often show weakness or partial fill, especially in finer details. Collectors should assess the overall evenness of the planchet, presence of casting flaws like pitting or rough edges, and the precise formation of the central square hole. Variability in metal flow and mold alignment can lead to differences in clarity and aesthetic appeal.
