In the US, every coin intended for circulation except for the 1943 steel penny used copper (even the gold coins were alloyed with copper), nickel is used in most modern circulating coinage (its what gives the dime, nickel, half-dollar, and quarter its silvery appearance), zinc is used in post-1982 pennies coated with a very thin layer of copper. Presidential and Sacajawea dollars are made with manganese brass, the 1943 steel penny was made out of steel, of course pre-1965 dimes, half-dollars, quarters contained silver. The US has made circulation-grade gold coins prior to 1933 and has made bullion and collector coins out of gold. The US has struck platinum bullion coins. In the 1970s the US struck some experimental coins in aluminum, but they were never released for circulation.
