My wife just pulled out a roll of Kennedy half dollars. There is a 1966, a few 1971 (d) and one 1977 (d). Are any of these worth anything other than face value?
1966 - 40% Silver - melt value about $2.25 1971 D - Circulated - Face value - MS+ up to $5.00 1977 D - Circulated - Face value - MS+ up to $2.50
