Which is the country that has only currency notes (bills), but no coins?

There are ten independent nations that don't use coins (or very rarely use them, such as with Vietnam or Guinea) as of 2012. These countries use paper money for all (or nearly all) currency transactions. In some cases, the nations used to produce coins, but inflation rendered them to be worthless (for instance, the highest denomination coin in Guinea is worth about 1 US cent).
