Cambodian riel
The riel (code: KHR) is the currency of Cambodia. There have been two distinct riel, the first issued between 1953 and May 1975, and the second since April 1, 1980. In Cambodia, the U.S. dollar is also widely used. Between 1975 and 1980, the country had no monetary system.
The 10, 20 and 50 centime of 1953 and sen coins were minted in aluminium and were the same size as the corresponding att and xu (su) coins of Laos and South Vietnam (though without the holes in the Lao coins). A 1 riel coin about the size of a U.S. nickel was to be issued in 1970 but was not released, perhaps due to the overthrow of the government of Norodom Sihanouk by Lon Nol.
