Ah, the 1964 Kennedy half dollar, the one-year wonder of the 90% silver world! It seems you've stumbled upon quite the treasure trove. Unlike its less-lustrous successors, the 1964 edition was packed with the good stuff.
According to the provided context, a single 1964 Kennedy half dollar contains 0.3617 troy ounces of pure silver. It's the undisputed champion of silver content in the Kennedy series.
Now, since you're the fortunate owner of 20 of these shiny historical pieces, we just need to do a little multiplication. When you gather all your coins for a family portrait, you are looking at a grand total of 7.234 troy ounces of silver. That's certainly more exciting than the ten bucks in face value they represent! It's a nice little stack of precious metal you've got there.
