Ah, the classic "Is this shiny disc in my drawer a tiny fortune?" question. Let's crack this numismatic nut. The value of a silver 50-cent piece isn't a simple one-size-fits-all answer, because it really depends on when your half dollar was born.
Think of it like this: you have two main categories of silver half dollars. First, you have the really good stuff, the 90% silver half dollars minted up to 1964. These are the heavyweights. Based on a silver spot price of $29.30 per ounce, one of these coins has a melt value of about $10.60. That's its baseline value just for the precious metal it contains. Not bad for fifty cents!
Then you have their younger, 40% silver cousins, which were minted from 1965 to 1970. They still have some precious metal swagger, but not as much. Their silver melt value hovers around $4.33. Still a handsome profit, but not quite the same as their older siblings.
Now, this is all before we even whisper the magic word: "collectibility." The values above are just the floor price based on the metal. If you have a coin from a rare year, with a specific mint mark, or in exceptionally pristine condition, its value could be much, much higher than the melt price. That's when you move from "silver value" to "rare coin value," which is a whole different ballgame. So, check that date! Your coin is worth at least a few bucks, but it could be a collector's prize.
