Currancy

Korea's currency unit is the Won. Coins are in denominations of W10, W50,W100, and W500. Bank notes are of 1,000, 5,000, and 10,000. Foreign bank notes and traveler's checks can be converted into Korean Won at foreign exchange banks and other authorized moneychangers.

The value of the Korean won to the US dollar fluctuate marginally, and banks and money changes charge commission. Similarly, commissions are payable in hotels and major retail outlets which provide exchange facilities for their customers. As elsewhere, the rates of exchange for cash and travellers' cheques are marginally different, and coins are not exchangeable.
