1 Mun; 2dot Tong Ho; To enter

The "To enter" designation on this mun identifies it as a coin struck for introduction into circulation from a specific government office — the Joseon court operated dozens of licensed casting bureaus simultaneously, each authorized to mint independently, which is why attribution by issuing office matters more than mint mark conventions familiar to Western collectors. The two-dot (2dot) Tong Ho notation distinguishes this die pairing within the Oseong classification system, a critical differentiator in a series where superficially identical coins can vary dramatically in collector value depending on office origin.

Production of mun coinage during this window coincided with persistent copper shortages that forced repeated royal edicts restricting and then re-authorizing various bureaus.
