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.
Korean currency
Korean currency dates back as far as the Goryeo dynasty (918–1392) when the first iron coins were minted. During that period, even though some imported Chinese currency was also in circulation, commodity currency such as grain and linen continued in general circulation.
