It really depends of what Kennedys you are talking about. Since you mentioned Franklins, I assume you are more interested in the 1964-1969 issues. The 90% 1964s are the most common 90% silver half dollars available, they typically trade at melt value. The 40% issues for 1965-1969 are also very common but due to low silver content, they typically trade for a bit under melt value. I did not include the 1970D since that one was only issued in Mint Sets and is almost never found in circulated condition. The 1971-current Kennedys are cupronickel clad and are typically only worth face value.
