COIN: A shiny metal disc, almost always authorized by a national government entity, with a raised impression of famous dead people on one side and a building or birds on the other that is used as money. U.S. coins are issued by the U.S. Treasury Department and come in denominations of pennies, nickels, dimes, quarters, half-dollars, and dollars. At one time, metal coins were comprised of valuable metal (that is, commodity money) in an amount equivalent to their face value. A dime had 10-cents worth of silver. A nickel had 5-cents worth of nickel. A penney had 1-cents worth of copper. Most modern coins, however, are fiat money, containing less valuable metal alloys. But they work just fine in vending machines.

PRODUCTION POSSIBILITIES CURVE A curve that illustrates the production possibilities of an economy--the alternative combinations of two goods that an economy can produce with given resources and technology. A production possibilities curve (PPC) represents the boundary or frontier of the economy's production capabilities, hence it is also frequently termed a production possibilities frontier (PPF). As a frontier, it is the maximum production possible given existing (fixed) resources and technology. Producing on the curve means resources are fully employed, while producing inside the curve means resources are unemployed. The law of increasing opportunity cost is what gives the curve its distinctive convex shape.
