A clad coin
is one that has multiple layers of metal in it; most current U.S. clad coins
consist of an inner core of copper, with outer layers of a silver-colored nickel-copper alloy
. Examples of this type of clad coin are the U.S. Dime, Quarter, and Half Dollar.
The golden dollar coins, including the Sacagawea Dollar
and the Presidential Dollars
, are also clad. They have a copper core with clad layers made from a zinc, manganese, and nickel combination.
On most U.S. clad coins
, if you look at the edge of the coin, you can see the copper core sandwiched between the outer layers of metal.
