Well, it seems the provided context is playing a bit of hide-and-seek, showing us the signs for the treasure map but not the map itself. No worries, as an expert in all things shiny and historical, I can fill in the blanks.
So, you've found a 1964 Kennedy half dollar! Before you run off to the candy store, you should know it's worth quite a bit more than fifty cents. That specific year is the belle of the ball for Kennedy halves because it was the first and only year they were minted with 90% silver. Every Kennedy half dollar made after that had its silver content drastically reduced, making your 1964 coin the real deal.
At the absolute minimum, your coin is worth its "melt value," which is the value of the silver it contains. This price changes daily with the silver market, but you can generally expect a 1964 half dollar to be worth around $10, give or take, based on its silver content alone. It's essentially a small silver ingot with a president's face on it.
Now, if your coin looks like it just rolled out of the U.S. Mint yesterday and has no scratches or signs of wear, its value starts to climb. Coin collectors will pay a premium for these uncirculated, or "Mint State," examples. The value could inch up to $15, $20, or even more depending on its pristine condition. There are also special "proof" versions made for collectors with a mirror-like finish that are worth a bit more. And if you have a super rare variety, like the "Accented Hair" proof, you're looking at a much bigger payday.
In short, while you probably won't be retiring early on a single 1964 half dollar, it's certainly a fantastic find that's worth a whole lot more than two quarters.
