Ah, the 1964 Kennedy half dollar! You've stumbled upon the rock star of pocket change. Asking what it's worth is like asking how much a classic car is worth; the answer is always, "it depends on the condition, darling." While the provided context was about as helpful as a screen door on a submarine, showing me the restaurant menu without the prices, I can certainly shed some light on this silvery treasure.
First and foremost, that 1964 half dollar is special because it's the only year the circulating Kennedy was made of 90% silver. This means its absolute minimum value is tied to the daily price of silver. Think of it less as a coin and more as a small, shiny metal ingot that happens to have a president on it. This "melt value" typically hovers somewhere around the $10 mark, give or take, depending on the whims of the market. So, at the very least, you can get a fancy lunch for it, which is a great deal for fifty cents.
But wait, there's more! If your coin looks like it just rolled out of the U.S. Mint yesterday and hasn't seen the grubby inside of a single vending machine, its value climbs. Coin collectors, a meticulous bunch, grade these on a scale from "seen better days" to "absolutely flawless." A standard, shiny uncirculated 1964 Kennedy might fetch $15 to $20. If it's a top-tier, certified specimen in near-perfect condition, the price can jump into the hundreds.
And if you're truly lucky, you might have a special variety, like the "Accented Hair" proof version, which is the rare, glamorous cousin of the standard coin. Those can be worth a whole lot more. So, the short answer is: it's worth a lot more than fifty cents. The long answer is: it could be worth the price of a movie ticket or the price of a plane ticket, all depending on how well it has aged.
