The Kennedy half dollar is one of the most recognized coins in American history. First minted in 1964 to honor President John F. Kennedy after his assassination, it quickly became a symbol of national pride and remembrance. Over the decades, the coin has undergone changes in composition, minting practices, and collector demand. In 2026, Kennedy half dollars continue to attract attention from numismatists and investors alike, with rare varieties and error coins commanding significant premiums. This guide explores their history, mint marks, value charts, and collector trends that define the market today.
The Origins of the Kennedy Half Dollar
The Kennedy half dollar was introduced in 1964, replacing the Franklin half dollar. Designed by Gilroy Roberts and Frank Gasparro, the coin features Kennedy’s portrait on the obverse and the presidential seal on the reverse. The first year of issue was struck in 90 percent silver, making it highly desirable among collectors.
From 1965 to 1970, the coin was produced in 40 percent silver. After 1971, circulation strikes were made in copper‑nickel clad, though special collector editions continued to be struck in silver. This shift in composition reflects broader changes in U.S. coinage as silver was phased out of everyday currency.
Mint Marks and Their Importance
Mint marks indicate where a coin was produced, and they play a crucial role in determining value. For Kennedy half dollars, the most common mint marks are:
- No mint mark: Philadelphia Mint
- D: Denver Mint
- S: San Francisco Mint (proof issues)
Mint marks are especially important for rare varieties. For example, certain San Francisco proof issues and Denver mint errors are highly collectible.

Several Kennedy half dollars stand out as highly valuable due to rarity, condition, or minting errors. Notable examples include:
