North Korean won
The won (; , ; symbol: ₩; code: KPW) or Korean People's won is the official currency of North Korea. It is subdivided into 100 "chon". The won is issued by the Central Bank of the Democratic People's Republic of Korea, based in the capital city, Pyongyang.
Korean mun
The mun was introduced as the main currency of Korea in 1633 and stayed in use until 1892. It resembled and was derived from the Chinese wen (cognate also to the Japanese mon, Ryukyuan mon, and the Vietnamese văn). Coins denominated in mun were cast in copper or bronze and were round with square holes. From the 17th century until the end of the 19th century, coins denominated in "mun" bearing the inscription "Sangpyeong Tongbo" (, ) were the most widely circulated currency. In 1888, coins were struck in small numbers denominated in mun and won (equal to 1000 mun). The mun was replaced in 1892 when the yang was introduced.
