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
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.
