This guide explores the history, design, rare varieties, and values of Kennedy Half Dollars, helping collectors understand why these coins remain so desirable in 2026.
History of the Kennedy Half Dollar
The Kennedy Half Dollar was introduced in 1964, replacing the Franklin Half Dollar. Designed by Gilroy Roberts (obverse) and Frank Gasparro (reverse), the coin was initially struck in 90 percent silver. Over time, the composition changed to 40 percent silver for special issues and eventually to copper‑nickel clad for circulation. The coin has remained in production for decades, though circulation demand has declined, making it more of a collector’s coin today.
Design Features
- Obverse: Portrait of President John F. Kennedy.
- Reverse: The Presidential Seal, featuring an eagle with a shield, olive branch, and arrows.
- Mint Marks: P (Philadelphia), D (Denver), S (San Francisco).
- Composition: 90 percent silver in 1964, 40 percent silver in special issues until 1970, copper‑nickel clad afterward.
