A useful history covering the ancient practices of bartering and using commodities (salt, grain, tobacco) as media of exchange, plus the development of metal and paper currency and contemporary cashless methods of payment; handsomely illustrated with many expansive landscape paintings resembling those in the Maestros' The Discovery of the America (1991), maps, and meticulous drawings of coins and bills. A simpler, more focused treatment than Cribb's Money (in the Eyewitness format, 1990). (Nonfiction/Picture book. 7-10.)
