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 currency
The country then had to switch over to a new currency unit named "hwan" replacing won at 1 hwan = 100 won. Like South Korean won, this currency unit was also issued in banknotes initially but in 1959, coins denominated in hwan were also issued and were the first circulating coins in South Korea. Hwan had a peg with US dollar but with time it also got devaluated. This was the reason for the reintroduction of won in 1962 as the official currency unit. South Korean currency was still pegged to the US dollar until in 1997 when it was floated into the world market.
