The composition of the 1971 Kennedy half-dollar is primarily copper-nickel clad, meaning it consists of a core of pure copper with an outer layer of a copper-nickel alloy. This construction contrasts with the earlier 1964 version which contained 90% silver, and the 1965-1970 issues which were comprised of 40% silver. Therefore, the 1971 issue does not contain any silver in its metallic makeup intended for circulation.
Understanding the metal composition of these coins is crucial for collectors and investors. The presence or absence of silver significantly impacts the coin’s intrinsic value, making it more than its face value. Coins composed with silver have a value connected to precious metal markets, in addition to any numismatic appeal it might possess. This contrasts with coins made of base metals which have a value solely related to its collectability or face value.
