Throughout most of history, most money has been commodity money, which is an item used for money that has intrinsic value. Gold, copper, and silver coins are common examples. One major problem with commodity money is that it's cumbersome to use for large purchases. Just think how many silver coins you may have to use to purchase a car or a house - you would literally need a treasure chest or more. Representative money solves this problem.
A commodity currency is a name given to currencies of countries which depend heavily on the export of certain raw materials for income. These countries are typically developing countries, e.g. countries like Burundi, Tanzania, Papua New Guinea; but also include developed countries like Canada and Australia.
