1964 was the first year that Kennedy halves were minted, so there aren't any pre-1964 JFK halves. Halves dated 1948-1963 are Franklin halves, and 1916-1947 are Walking Liberty halves. All of these are made of 90% silver so they're worth at least $7 for their silver content alone, possibly much more as collectibles. Please post a new question with the coin's date.
When a coin has a hole in it, it takes a lot away from the value. If it is 1964 or older, it is still worth something for the silver, maybe $10.
