Issued under Sukjong of Goryeo, this coin belongs to Korea's first serious attempt at a state-managed copper currency economy. Despite official encouragement — including royal decrees incentivizing merchants to accept coin over cloth and grain — the campaign largely failed. Korean commercial culture remained stubbornly wedded to commodity exchange, and most of these coins saw limited active circulation before the experiment was effectively abandoned by the mid-twelfth century.
