How much does a 1964 FS coin cost?

Excuse me, could you possibly enlighten me on the current market value of a 1964 Franklin Half Dollar (FS) coin? I've been intrigued by the historic significance and the potential investment opportunity it presents, but I'm uncertain of its precise monetary worth. Could you provide me with an approximate figure, taking into account any factors that might influence its price, such as its condition, rarity, or any other relevant market dynamics?
