Korean Won

The won (圓) was the currency of Korea between 1902 and 1910. It was subdivided into 100 chon (錢).

Etymology
Won is a  cognate of the Chinese yuan and Japanese yen.

History
The won was introduced in 1902, replacing the yang at a rate of 1 won = 5 yang. In 1909, the Bank of Korea (韓國銀行) was founded in Seoul as a  central bank and began issuing currency of a modern type. The won was equivalent to the Japanese yen and was replaced by the Japanese currency and the Korean yen in 1910 when Korea lost its sovereignty to Japan. In 1910, the Bank of Korea was renamed the Bank of Joseon (朝鮮銀行), which issued notes denominated in yen and sen.

Coins
Coins were minted in the denominations of ½, 1, 5, 10 and 20 chon, ½, 5, 10 and 20 won. The coins all carried the title of the "state", Daehan (대한; 大韓), and the  Korean era name, Gwangmu (광무; 光武) and then Yunghui (융희;隆熙), whilst the specifications were equivalent to the coins of the Japanese yen.

Banknotes
No banknotes were issued denominated in won. However, Korean yen notes were issued by Dai Ichi Ginko (First National Bank (of Japan), 株式會社第一銀行).
