Etymology of the Korean currencies
The won is the currency of both North and South Korea. "Won" is a cognate of the Chinese currency unit, the yuan (//), and the Japanese currency unit, the yen (; ¥), meaning "round object". The won is subdivided into 100 jeon ().
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.
