The hwan suffered from inflation as well. At its introduction, it was pegged to the United States dollar at 1 dollar = 60 hwan, but toward the end of its life it was devaluated at 1 dollar = 1250 hwan. In 1962, the won was reintroduced at the rate of 1 won = 10 hwan. The 10 and 50 hwan coins were kept in circulation until March 21, 1975. After the devaluation of the hwan, the won was reintroduced as South Korea's currency on June 10, 1962. At the time the South Korean currency was still pegged to the US dollar. It stayed so until December 24, 1997, when it became a floating currency, but was then immediately devalued at nearly half of its value because of the East Asian financial crisis.
