That's a great question! The weight of a silver fifty-cent piece, or half-dollar, depends on the specific year it was minted. While the provided context didn't contain the specific details on coin weights, I can certainly provide you with the information.
The most common silver half-dollars you'll find, those minted in 1964 or earlier, weigh 12.5 grams. This standard weight applies to the Barber, Walking Liberty, Franklin, and the 1964 Kennedy half-dollars. These coins have a composition of 90% silver and 10% copper.
From 1965 to 1970, the U.S. Mint produced Kennedy half-dollars with a reduced silver content of 40%. These coins weigh slightly less, at 11.5 grams. After 1970, circulating half-dollars no longer contained any silver. So, if you have a silver one, it will most likely be one of those two weights
