This is a Sangpyeong Tongbo coin issued and minted by the Joseon Dynasty between AD 1633 and AD 1882. Based on the quality of the casting, it is highly likely that this specimen was privately minted by non-governmental sources.
The coin features a square-holed design, a form heavily influenced by neighbouring China. Although the surface is heavily worn, the obverse side still faintly reveals the four Chinese characters Sangpyeong Tongbo (常平通寶), inscribed in the traditional order of top, bottom, right, and left. The term Sangpyeong does not correspond to any regnal era of a Joseon monarch; rather, it derives from the Sangpyeongcheong, a government office responsible for providing relief to the poor.
The upper edge of the coin’s reverse side bears a heavily worn Chinese character, rendering the identity of the issuing authority indiscernible. At the bottom, the character (日), meaning “sun” and derived from the Thousand Character Classic (Cheonjamun), is still faintly visible. On both the left and right sides, there appear to be geometric lines resembling crescent or moon motifs, likely serving as decorative elements.
Sangpyeong Tongbo was a form of currency circulated during the Joseon Dynasty, with its minting period spanning from AD 1633 to AD 1894. Over the course of its production, more than 3,000 distinct varieties of this coin type were issued. Even after Korea was annexed by Japan in the early 20th century, Sangpyeong Tongbo continued to be used by commoners in everyday transactions, particularly in more remote regions during the initial years of Japanese colonial rule.
