what year was the kennedy half dollar all silver

[StPeyton]

Ah, the great silver hunt! If you're looking for the year the Kennedy half dollar was the real silver deal, you'll need to set your time machine to one specific year.

The only year the Kennedy half dollar was minted with a glorious 90% silver composition was in its debut year, 1964. It was a true one-year wonder in that regard. After that, the U.S. Mint began to slowly phase out the precious metal. The composition changed over time, first reducing the silver content and then eventually eliminating it from circulating coins altogether.

So, if you're rummaging through old coin jars, the 1964 Kennedy is the big silver prize you're looking for. Any other year is a different story.
