1 Mun Cursive script

Cast during the reign of Sukjong of Goryeo, these coins were part of a deliberate state effort to displace barter and cloth currency in everyday exchange — an effort that largely failed. Korean merchants and peasants resisted metallic currency with remarkable stubbornness throughout the dynasty, preferring grain and fabric for transactions well into the following century.

The cursive script designation distinguishes this casting from the regular script issues of the same period, a variation attributed to different foundry workshops rather than any official policy distinction.
