50 Hwan

South Korea introduced the Hwan in 1953 as a redenomination of the war-ravaged Won, replacing it at 100:1 in a bid to stabilize an economy shattered by the Korean War. The 50 Hwan was part of the first substantive coinage program the newly independent Bank of Korea could call its own. The Hwan itself proved short-lived — a 1962 currency reform abolished it entirely, again at 10:1, folding it into the new Won.

The 1959–1961 window means surviving examples saw at most three years of circulation before demonetization.
