I assume you are asking about “clad” coinage and not the usual alloy of copper and nickel that is common in many world coins as well as the United States nickel. The clad metal strip used for blanks on U.S. coinage, 10c and higher, is fabricated by bonding both sides of a central core to thinner layers. So a clad blank contains nickel bonded to a central core of pure copper.
