Circulating US Coins from the nickel to the dollar are mostly copper. Nickels are 75% copper and the others are around 90% copper depending on their denomination.

However the famous "copper" penny has been mostly zinc since mid-1982. The outer coating only makes up about 2.5% of the coin by weight, or 0.0625 gm.

The link below shows the specific weights, metals, and sizes of all current coins.
