Introduce the Kennedy Half Dollar series, which transitioned from 40% silver to a clad composition in 1971. These coins are still in production today, featuring a 75% copper and 25% nickel alloy.
Discuss the design elements of the Kennedy Half Dollar, which retains the obverse portrait of John F. Kennedy by Gilroy Roberts and the reverse featuring the Presidential Seal by Frank Gasparro.
Explain the shift in composition from 40% silver to a copper-nickel clad metal beginning in 1971, a response to rising silver prices and the need for more economical coin production.
Describe how the clad Kennedy Half Dollars have been minted in vast quantities at the Philadelphia, Denver, and San Francisco mints, with occasional proof, uncirculated, and commemorative versions released.
Highlight the 75% copper and 25% nickel composition used in these coins, which are more durable and cost-effective than silver coins, but they lack the precious metal value that once characterized the Kennedy Half Dollar.
Discuss significant years and special editions in the series, including the 1992 commemorative issue for the 200th anniversary of the signing of the U.S. Constitution, the 1995-W proof with a low mintage, and the 2014 enhanced uncirculated coin.
Explain the different types of coins available in this series, including the high-quality proof coins minted at the San Francisco Mint and the uncirculated versions, which are popular with collectors for their pristine condition and intricate details.
Discuss the collectibility of the clad Kennedy Half Dollars, particularly for high-grade examples, complete sets, and commemorative issues.
