Laos and Belarus use only paper money. Laos is one of the poorest countries in the world with only $1 in circulation per capita.
Nearly every country uses coins for small currency amounts. At this writing (2016) only Belarus and Laos don't use coins, mostly because their currencies are so devalued that coins cost more to make than they are worth.
The currency of Belarus is the Belarusian ruble (BYR).
