The title of "most valuable" depends on the coin's condition. For most conditions, Numismedia's price quotes show the most valuable Franklin half dollar is dated 1949 and carries an S mint mark above the bell on the reverse. Retail prices as of 04/2009 exceed the values of all other dates and mint marks, up to the condition MS-65.
However, a few dates in higher conditions command higher prices. Prices of 1949-S halves don't rise that much at the upper end of the MS range, but other dates such as 1949 plain, 1953-D, and 1959 plain far exceed the value of a 1949-S in grades MS-66 to MS-70.
