Economy of North Korea
Estimating gross national product in North Korea is a difficult task because of a dearth of economic data and the problem of choosing an appropriate rate of exchange for the North Korean won, the nonconvertible North Korean currency. The South Korean government's estimate placed North Korea's GNP in 1991 at US$22.9 billion, or US$1,038 per capita. In contrast, South Korea posted US$237.9 billion of GNP and a per capita income of US$5,569 in 1991. North Korea's GNP in 1991 showed a 5.2% decline from 1989, and preliminary indications were that the decline would continue. South Korea's GNP, by contrast, expanded by 9.3% and 8.4%, respectively, in 1990 and 1991.
North Korean won
Initially struck in 2002, the coins were intended for use shortly after the dollar peg was removed from the currency. The 50 chon and 1 won were smaller than the previous designs, while the new 10 chon was the same size as the old. Hyperinflation became a very sudden reality, however, and the new coins were never released as planned. In 2008, 1 and 5 chon coins were also struck when a plan for monetary revaluation began. The coins were finally released into circulation in December 2009 but due to the flawed nature of the revaluation these coins again carry very little value, with especially the 1 and 5 chon being virtually irrelevant.
