Well, the provided search results are about as helpful as a chocolate teapot, offering a website's menu but none of the actual prices. So, let's set that aside and dive into the real story of the Kennedy half dollar.
The tale of what your 50-cent piece is worth is really a story of heavy metal, or more accurately, the gradual disappearance of it. The most important question to ask your coin is, "What year were you born?" The answer dramatically changes its value from pocket change to a nice little silver bonus.
The undisputed rockstar is the 1964 Kennedy half dollar. This was the first and only year the coin was made of 90% silver. It's the one everyone hopes to find in their grandparent's old coffee can. Its base value is tied to the fluctuating price of silver, but it's always worth significantly more than its 50-cent face value.
From 1965 to 1970, the coins went on a diet, slimming down to a 40% silver composition. Think of these as the "silver-lite" years. They still carry a value above 50 cents based on their silver content, but they aren't the heavyweight champion that the '64 is.
After 1970, the party was over. The silver was completely removed, and the coins were made from a common copper-nickel blend. So, for most Kennedy half dollars minted from 1971 to today, they are worth... exactly 50 cents. I know, it's a shocking twist. The exceptions are special-issue proof coins or silver versions made specifically for collectors, but the average coin you find in circulation from these years is just face value. In short, check for a date that starts with "196" to see if you've got more than just two quarters in your hand.
