1 Mun Cursive script

Issued under King Sukjong, who made the most sustained attempt in Goryeo's history to establish a functioning coin economy in a kingdom where cloth and grain had served as exchange media for centuries. The cursive script variant is attributed to the same reform push that produced multiple calligraphic styles across a single denomination — a deliberate signal of imperial sophistication rather than a functional distinction.

The experiment largely failed. Merchants and commoners continued preferring commodity currency long after Sukjong's death in 1105.
