Following the end of the Colonial Era and the division of Korea, the won was introduced to replace the Korean yen. The first banknotes were issued by the Bank of Joseon until 1950, when the currency management switched to the Bank of Korea. At the time of its introduction in 1945 the won was pegged to the Japanese yen at a rate of 1 won = 1 yen.
Due to the devaluation of the first South Korean won (from 15 won to the U.S. dollar in 1945 to 6000 won to the dollar in 1953), the hwan was introduced in 1953 at the rate of 1 hwan = 100 won. The hwan was nominally subdivided into 100 jeon but the lowest denomination issued was 1 hwan.
The hwan suffered from inflation as well. At its introduction, it was pegged to the United States dollar at 1 dollar = 60 hwan, but toward the end of its life it was devaluated at 1 dollar = 1250 hwan. In 1962, the won was reintroduced at the rate of 1 won = 10 hwan. The 10 and 50 hwan coins were kept in circulation until March 21, 1975.
In 1982, with inflation and the increasing popularity of vending machines, 500 won coins were introduced on June 12, 1982. In January 1983, with the purpose of standardizing the coinage, a new series of 1, 5, 10, 50, and 100 won coins was issued, using the same layout as the 500 won coins, but conserving the coins' old themes.

Coin values can be modeled by a set of n distinct positive integer values (whole numbers), arranged in increasing order as w 1 through w n.The problem is: given an amount W, also a positive integer, to find a set of non-negative (positive or zero) integers {x 1, x 2, ..., x n}, with each x j representing how often the coin with value w j is used, which minimize the total number of coins f(W)
U.S. job gains over the 12 months ending in March were revised downward Wednesday by 818,000 — a significant revision that adds to recent concerns that the economy has been slowing.

Bronze coins were cast starting in 1423 during the reign of king Sejong the Great with the Joseon Tongbo (조선통보, 朝 鮮 通 寶) cash coins. [7] [5] The coins produced under Sejong were pegged to copper at 160 coins to one Kŭn (斤, 근) which is equal to 600 grams, though the actual market rates regularly fluctuated. But the monetary ...
