Etymology of the Korean currencies
The won is the currency of both North and South Korea. "Won" is a cognate of the Chinese currency unit, the yuan (//), and the Japanese currency unit, the yen (; ¥), meaning "round object". The won is subdivided into 100 jeon ().
Korean currency
Following the end of the division of Korea, the won was introduced to replace the Korean yen. The won was subdivided in 100 jeon. The first banknotes were issued by the Bank of Joseon in denominations ranging from 5 jeon to 100 won. In 1950 the currency management switched to the Bank of Korea and new notes were then issued, mostly with higher denominations.
