Well, let's get ready to either celebrate or manage expectations. The first thing to know about your 1971 half dollar is a little bit of a plot twist: it's not actually silver. I know, I know, it feels like a betrayal. The U.S. Mint stopped putting silver in circulating Kennedy half dollars after 1970, switching to a copper-nickel clad composition. So, its melt value is, to put it kindly, negligible.
For the vast majority of 1971 half dollars that have seen the inside of a cash register or a piggy bank, their worth is exactly what it says on the coin: 50 cents. You can't retire on it, but you can probably buy something from a gumball machine. So, if your coin looks like it's been on a world tour, its journey is likely to end at the bank.
However, don't toss it in the "spend" pile just yet! There is a silver lining, just not a literal one. If your coin is in pristine, uncirculated condition, its value gets a nice little bump. Collectors might pay anywhere from a dollar to a few bucks for a shiny, unblemished example from the Philadelphia or Denver mints. If it has an "S" mint mark, it's a proof coin made for collector sets and could be worth around three dollars or more depending on its condition.
And for the true treasure hunters, there are rare error coins out there, like the famous "No FG" variety where the designer's initials are missing from the back. Find one of those, and you're talking about a coin worth substantially more. So, in short: it's almost certainly worth 50 cents, but it's worth a quick look just in case it's a supermodel of the coin world.
