| Additional information |
The "arranged in order" designation refers to the oshi system of mint identification used by Joseon's military and government offices, where reverse characters indicated the issuing bureau and sequential cast number — a bureaucratic control mechanism introduced as the dynasty struggled to regulate a flood of privately cast counterfeits that had badly debased the sangpyeong tongbo currency supply through the early eighteenth century. The 1742 authorization tightening cast coin oversight came directly from the Bibyeonsa, the Border Defence Council, which had assumed de facto control over monetary administration.
