Which of the following is the official currency of South Korea?

The South Korean won, officially the Korean Republic won is the official currency of South Korea. A single won is divided into 100 jeon, the monetary subunit. The jeon is no longer used for everyday transactions, and it appears only in foreign exchange rates. The currency is issued by the Bank of Korea, based in the capital city of Seoul.

The Korean won, Chinese yuan and Japanese yen were all derived from the Spanish-American silver dollar, a coin widely used for international trade between Asia and the Americas from the 16th to 19th centuries.

During the colonial era under the Japanese (1910–45), the won was replaced by the Korean yen which was at par with the Japanese Yen.

After World War II ended in 1945, Korea was divided, resulting in two separate currencies, both called won, for the South and the North. Both the Southern won and the Northern won replaced the yen at par.
