That's a fantastic question, and discovering the value of a Kennedy half dollar is your first step into a fascinating piece of American numismatic history. The value isn't just one single number; it's a story told primarily by the coin's date, which determines its silver content.
The most important year you need to look for is 1964. This inaugural issue, struck shortly after President Kennedy's death, is the only circulation Kennedy half dollar made of 90% silver. Because of this high silver content, its base value is tied directly to the current price of silver, making it worth significantly more than its 50-cent face value. Even in circulated condition, these coins are highly desirable.
After that pivotal first year, the composition changed. From 1965 to 1970, Kennedy half dollars were produced with a 40% silver-clad composition. While not as valuable as the 1964 issue, they absolutely carry a premium over their face value due to their silver content. They are a treasure to find in your pocket change. Kennedy half dollars made for circulation after 1970 contain no silver and are generally only worth their face value.
Beyond the silver melt value, which you can determine from price guides like those mentioned in the search results, a coin's condition is a major factor. A pristine, uncirculated coin from 1964, for example, will command a much higher price from collectors than a worn one. So, the first and most crucial step is to check the date on your coin. That will tell you almost everything you need to know about its potential worth.
