The Kennedy Half Dollar is one of the most iconic coins in American numismatic history. Minted as a tribute to President John F. Kennedy after his assassination in 1963, the coin has been in circulation since 1964.
While most Kennedy Half Dollars are common and relatively low in value, a few rare editions can fetch staggering prices with one specific coin valued at an amazing $250,000. But what makes this particular half dollar so special? Let’s dive deep into the details.
The Origins of the Kennedy Half Dollar
After the death of President John F. Kennedy, on November 22, 1963, the American government came to a decision to hold a shoot-too-late tribute in honor of the tragic event. Among those tributes was a change in the design of the Franklin Half Dollar so that it would bear the likeness of JFK.

Speedy production procedures for this newly designed coin were taken; thus, the first Kennedy Half Dollars made their appearance in March of 1964. The coin was also widely admired and hoarded by the public and collectors alike. Consequently, many of them never reached normal circulation a status that still impacts their availability to this day.
What Makes a Kennedy Half Dollar Valuable and Rare?
Not all Kennedy half dollars are equal. While most are worth face value or a little more, some characteristics and conditions render some editions extremely rare and sought after. These are
1. Mint Errors
Coins with mint errors like double dies, off-center strikes, planchet problems, or omitted mint marks are highly valuable. The visibility and rarity of the error significantly influence the value.
2. Year of Issue
The 1964 Kennedy Half Dollar is the sole one that was produced with 90% silver, so it is more valuable based on metal content alone. They were produced with 40% silver between 1965 and 1970. Post-1970 coins are normally produced with copper-nickel unless produced as special collector’s items.
3. Mint Location
Coins minted at other mints (Denver “D,” San Francisco “S,” or Philadelphia with no mark) differ in their numbers of production. The 1964 SMS (Special Mint Set) Kennedy Half Dollar, presumably minted in the Philadelphia Mint, is exceptionally rare.
4. Condition and Grade
Coins in near Mint State (MS-67 or better) condition or with a Proof stipulation are much more valuable. Grading by well-regarded agencies such as PCGS or NGC only adds value and marketability to a coin.
