2 Mun Chong, Ch'uk

The "Chong" series of cash coins was authorized under King Yeongjo as part of a broader effort to stabilize a copper currency that had been plagued by regional counterfeiting and unauthorized private casting since the late seventeenth century. The Joseon court had repeatedly suspended and reinstated copper coinage across the preceding decades, and this issue falls within a period of cautious re-expansion. The Ch'uk cyclical date narrows production to 1757 — a single year within the authorized range, if the date refers to the casting year rather than the series authorization.
