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.
Convertibility
Some countries pass laws restricting the legal exchange rates of their currencies or requiring permits to exchange more than a certain amount. Some currencies, such as the North Korean won, the Transnistrian ruble, and the Cuban national peso, are officially nonconvertible and can only be exchanged on the black market. If an official exchange rate is set, its value on the black market is often lower.
