Korean yen
The Korean yen was the currency of Korea between 1910 and 1945. It was equivalent to the Japanese yen and consisted of Japanese currency and banknotes issued specifically for Korea. The yen was subdivided into 100 sen. It replaced the Korean won at par and was replaced by the South Korean won and the North Korean won at par.
North Korean won
Since 2001, the North Korean government has abandoned the iconic rate of 2.16 won to the dollar (which is said to have been based upon Kim Jong-il's birthday, February 16) and banks in the country now issue at rates closer to the black market rate. More recent official rates have shown the North Korean won () to be ₩129.559 to the US dollar. However, rampant inflation has been eroding the North Korean won value. A report by defectors from North Korea claimed that the black market rate was ₩570 to the Chinese yuan (or about ₩4,000 per U.S. dollar) in June 2009. As of December 6, 2018, xe.com, a website that publishes mid-market currency exchange rates, lists the exchange rate at ₩900.073 to US$1.00.
