Ah, the Kennedy half dollar! The coin that asks the eternal question: "Am I just 50 cents, or am I a tiny silver treasure?" While the provided context points us to some excellent resources, it's a bit like getting a restaurant menu without any of the delicious details or prices. So, let's fill in the blanks.
The value of an uncirculated Kennedy half dollar depends almost entirely on its birthday. Think of the 1964 Kennedy as the original rock star of the series. Made of 90% silver, its base value is tied to the current price of silver, which means it's worth many times its face value. An uncirculated one carries an even higher premium for its good looks.
From 1965 to 1970, the coin went on a diet, dropping to 40% silver. These are still worth more than 50 cents due to their silver content, but they're the opening act, not the headliner. An uncirculated version from this era is a nice find, but it won't pay your rent.
After 1970, with a few exceptions for special collector sets, the Kennedy half dollar shed its silver and donned a practical copper-nickel clad suit. Most uncirculated coins from 1971 to today are worth a bit more than face value, perhaps a dollar or two. They're handsome but aren't typically the big-ticket items collectors chase, unless they're graded in near-perfect condition. So, an uncirculated Kennedy can be worth a nice chunk of change or, well, just change. It all comes down to the date on the coin.
