All current US Coins contain copper, as well as nickel, zinc and/or other metals.
Pennies (US cents) are normally referred to as "copper" coins, because they are plated with copper on the outside. However, they have less copper than any other coin (just 2.5%) and are mostly the 97.5% zinc that is inside.
Nickels (US 5 cents) are made of 75% copper and 25% nickel.
The clad denominations (dimes, quarters, and half-dollars) are about 92% copper; they have a pure copper core and outer layers of cupronickel in a "sandwich".
The newest US dollar coins (Sacajawea and Presidents) are brass coins containing 77% copper, with zinc, manganese, and nickel.
