United States coins are made out of a few different types of metals. Pennies (1-cent coins) are made of copper and zinc. The zinc is actually on the inside, so we only see the copper color on the outside! A nickel (5-cent coin) is made out of copper and another metal that is called nickel. That should be pretty easy to remember! Dimes (10-cent coins), quarters (25-cent coins) and half dollars (50-cent coins) are made of three really thin sheets of metal that get pressed together. The outside layers of metal are copper and nickel.
