1 Mun; Large Type Yong

Historical Context: The 1 Mun "Large Type Yong" coin, issued in 1742, hails from the Joseon Dynasty (1392-1897) during the reign of King Yeongjo (1724-1776). Yeongjo's long and stable rule marked a period of significant social and economic reform, aimed at strengthening the kingdom after earlier political turmoil. As part of the extensive Sangpyeong Tongbo (常平通寶) series, meaning "Always Level and Circulating Treasure," this coin was a fundamental unit of currency, crucial for facilitating daily commerce, taxation, and trade across Joseon Korea. Its continued production underscored the government's commitment to a standardized and reliable monetary system.

Artistry: Joseon coinage, particularly the Sangpyeong Tongbo series, adheres to a highly functional and calligraphic aesthetic rather than elaborate pictorial artistry. Specific engravers are generally unrecorded for these mass-produced cast coins. The design school emphasizes clear, legible characters rendered in a standardized regular script (Kaishu). The obverse prominently displays the four characters "Sangpyeong Tongbo," read top-bottom-right-left. The "Large Type Yong" refers to a specific, larger rendition of the character "用" within "Tongbo," a subtle yet important stylistic variation. The reverse typically features a single character indicating the mint or a series mark, reflecting the decentralized casting operations.

Technical/Grading: This 1 Mun coin, cast in brass with a weight of 4.8 grams and a diameter of 23 millimeters, is typical for its type. For cast coinage, technical quality is assessed by the sharpness and completeness of the characters, the evenness of the flan, and the clarity of the central square hole. High-quality examples will exhibit crisp definition in the "Sangpyeong Tongbo" inscription, particularly the distinguishing "Large Type Yong" character, with minimal casting flaws such as sand holes or uneven edges. The central hole should be cleanly punched or cast, and the rim relatively well-formed, indicating careful production from the various government or provincial mints.
