Korean currency
The yen was the currency of Korea during the Colonial rule, from 1910 to 1945, and was issued by the Bank of Joseon It was equivalent to the Japanese yen and consisted of Japanese currency and banknotes issued specifically for Korea. It was replaced by the South Korean won at par in 1945, and by the North Korean won in 1947.
North Korean won
In 1992, another redesign was carried out for banknotes, again in denominations of 1-, 5-, 10-, 50-, and 100-won. Older notes were once again withdrawn. These notes were smaller and crisper than the previous issue and depicted more modern themes. The 5 and 10 won banknotes were again issued in 1998, along with a 500 won banknote that same year but were stamped rather than engraved reflecting poorer production quality. In 2002, 1,000 and 5,000 won notes were introduced, followed by a 200 won note in 2005. The former two were identical in design to the 100 won though differing in colors and added security features, but the colored fields behind the text no longer extended all the way to the margins. In 2007, the 500 won had also been revised in this same manner along with being engraved for the first time to protect against counterfeiting. From 1998 onwards, all notes were dated using the Juche year along with the standard dating.
