| 正面描述 | Cast round coin with a central square perforation, typical of East Asian cash coinage. Four Chinese characters in regular script (kaishu) are arranged in cruciform fashion around the central square hole: 朝 (top), 鮮 (bottom), 通 (right), and 寶 (left), reading top-to-bottom and right-to-left as 朝鮮通寶 (Joseon Tongbo, meaning 'Joseon currency'). The characters are raised in low relief against a flat, unadorned field. An outer raised rim encircles the coin, with a corresponding inner rim framing the square perforation. The surface shows the dark, oxidized patina characteristic of iron or iron-alloy cast coinage. |

| 背面描述 | The reverse is blank and featureless, with a flat, unadorned field bounded by an outer raised rim and an inner rim surrounding the central square perforation. No legends, symbols, or mint marks are present. The surface displays the same heavily oxidized, dark patina as the obverse, consistent with the iron or iron-alloy composition of this cast cash-type coin. |

The Cho Son Tong Bo was introduced under King Sejong as part of a broader push to establish coin-based commerce in a kingdom where cloth and grain stubbornly persisted as the dominant exchange media. Iron-alloy issues like this one were minted precisely because copper was chronically scarce on the peninsula — a problem that would continue to undermine Joseon coinage policy for generations. Popular resistance to metallic currency remained so entrenched that the government eventually abandoned the effort entirely; coins would not circulate with any real success in Korea until the late seventeenth century.
