Full Answer

Half-dollar coins are made of a nickel-copper alloy, the U.S. Mint states. Only 8.33 percent of the alloy is nickel, with the remaining nearly 91 percent of the alloy consisting of copper and hardening additives. Federal Reserve Banks can only collect coins that have been worn down. If a coin has been adulterated or mutilated, it must be sent directly to the U.S. Mint in Philadelphia.
