Our list of the 10 Cheapest Currencies in the World in 2017 begins with the Cambodian Riel. The first riel was issued between 1953 and 1975. In 1980, the second currency, also known as riel, was rolled out. Today, most significant purchases in Cambodia are paid for in US dollars. ATMs likewise dispense money in this global currency. It is very rare to spot riel coins, as the Cambodian central bank has ceased to produce anything metallic.
