Ah, the 1964 Kennedy half dollar, a true classic! While the provided sources were about as revealing as a sealed envelope, offering titles but no treasure, I can certainly fill in the blanks for you. That half dollar in your pocket is worth a whole lot more than two quarters.
First and foremost, the 1964 Kennedy half dollar is a rockstar in the coin world because it's the last year the coin was minted for circulation with a glorious 90% silver content. This means its primary value isn't fifty cents; it's whatever the silver market says it is. Think of it less as pocket change and more as a tiny silver ingot with a president's face on it.
Because its value is tied to the fluctuating price of silver, there's no single, fixed price. However, a common, circulated 1964 half dollar is typically worth its "melt value," which these days often hovers somewhere in the $9 to $12 range. So, finding one in an old coin jar is definitely a win.
Now, if your coin looks like it just came from the mint yesterday and has avoided the dings and scratches of a hard life, collectors will pay a premium. An uncirculated 1964 Kennedy can easily fetch $20 or more. If you happen to have a special "proof" version with what's known as "accented hair," you're in an entirely different league, as those can be worth hundreds. So, the short answer is that it's worth a good bit, and the longer answer is it depends on its condition and the mood of the precious metals market.
