12 rolls of silver half dollars

I have 12 rolls of silver Liberty and Franklin half dollars that range in dates from the 1930s through the mid 1960s.

Most are very well circulated as shown in the attached picture. Given the condition, are there any that would be worth more than melt value? For example, a year/mint combination that had very few produced.

Also per coin what would be an approximate reasonable price for the melt value these days?
