North Korea
North Korea has the structural profile of a relatively industrialized country where nearly half of the Gross Domestic Product is generated by industry and human development is at medium levels. Purchasing power parity (PPP) GDP is estimated at $40 billion, with a very low per capita value of $1,800. In 2012, Gross national income per capita was $1,523, compared to $28,430 in South Korea. The North Korean won is the national currency, issued by the Central Bank of the Democratic People's Republic of Korea.
Superdollar
It has been confirmed that North Korea has passed off superdollars (Korean: "kattalio") in various countries. The counterfeit bills also circulate both within North Korea and around its border with China. There is, however, some doubt about the reliability of North Korean defectors' claims, on which the United States partially bases its accusations, along with South Korean intelligence sources.
