While the provided search results point to excellent resources like Greysheet and APMEX for coin pricing, they don't contain the specific values themselves. Drawing from general numismatic knowledge, I can tell you that unlocking the true value of your Kennedy half dollars is an exciting treasure hunt that depends almost entirely on their year. You might be holding much more than just fifty cents.
The most important year to look for is 1964. This was the first year of issue and the only year the coin was struck from 90% silver. Because of this high silver content, a 1964 Kennedy half dollar will always be worth many times its face value, with its base price tied directly to the fluctuating spot price of silver. It's the key coin that every collector and enthusiast seeks out from this series.
From 1965 through 1970, the composition was changed to a 40% silver clad. While not as valuable as the 1964 issue, these coins still contain a significant amount of silver and carry a premium value well above fifty cents, again based on the price of silver. It's always a great find to discover one of these in your pocket change.
Any Kennedy half dollar dated 1971 or later is made from a copper-nickel clad composition and contains no silver. These are the coins you are most likely to encounter in circulation. For the most part, these are only worth their face value of fifty cents. However, special issues for collectors, like proof coins or those in exceptionally pristine, uncirculated condition, can be worth a few dollars or more to the right buyer. So, the key is to check the date first; it's the fastest way to determine if you have a common coin or a valuable piece of silver history.
