Many coinage metals (or alloys) are from the three nonradioactive members of Group 11 of the Periodic table (copper, silver and gold); however there are many, even for coins made from intrinsically precious metals. Precious metals are always used in bullion coins and some collectable coins. Coins not intended for circulation or for intrinsic value have also been made experimentally using an even larger variety of metals, since they function as fiat money. In general coins intended for circulation must have metal values considerably less than their face values, for reasons discussed below.
