Lot of 40, $20 Face Value 1964 Kennedy Silver Halves, Unc?

These beautiful coins were given to my husband by his Grandfather (who was a VP at First National City Bank) in 1964. They have been stored in the original rolls (see pics) in a lock box since then. I am not a coin collector, so I cannot tell for certain whether or not these coins have been circulated, but they are in really good condition; although some discoloring has taken place during storage. Please take a close look at the pictures and feel free to ask questions or ask for more pics if needed.
These coins will be shipped via Small Flat Rate Box, Insured. I will only ship this item to the U.S.
