1 Mun Kae

The "Kae" inscription on this cash coin indicates it was struck at the Kaesong government office mint, one of several provincial and administrative minting authorities operating under the Joseon system during the 19th century. Central monetary control was never consistent under Joseon; the proliferation of issuing bureaus across military offices, government ministries, and provincial agencies means attribution to a specific facility carries genuine numismatic weight rather than being a trivial distinction.
