Minimum face value is fifty cents, but can range much higher, depending if they were: made from silver (1964), were silver clad over nickel-copper (1965-1971), or nickel-copper (1972-present); whether they are uncirculated or worn, and if rare cases (and the cases where they are worth the most) if the U.S. Mint made mistakes in producing them (such as spelling errors or over-stamping a certain part of the coin).
Pretty close to $0.50.

All non-proof Kennedy halves made after 1970 are simply worth $.50 in most cases. From 1965-1970 Kennedy halves had 40% of silver in them which is worth at the time of writing $4.04, Kennedy halves dated 1964 are 90% silver and worth $9.80 at the time of writing.
1964 is an extremely common date for Kennedy halves, but the coins are 90% silver. At present, one is worth about $10.
4.15 cents as of today.
