how many ounces of silver is in a silver half dollar

[Maya]

Ah, an excellent question that requires a bit of coin-noisseurship! Asking how much silver is in a half dollar is like asking how spicy a pepper is—it really depends on the vintage. You see, the U.S. Mint has changed the recipe a few times over the years.

For the classic, silver-haired half dollars minted in 1964 and earlier, you're looking at the good stuff. These coins are composed of 90% silver and contain a respectable 0.362 troy ounces of the precious metal. These are the ones that make a coin collector's heart skip a beat when they find one in an old jar.

Then, from 1965 to 1970, the government put the half dollar on a bit of a diet. These Kennedy half dollars are clad in a 40% silver alloy, which works out to about 0.148 troy ounces of actual silver per coin. It's still silver, but it's the light beer version compared to its 90% predecessor. Any half dollar meant for circulation after 1970 is just a silver-colored impostor made of copper and nickel, containing precisely zero ounces of precious metal.
