I have a 1776-1976 Kennedy clad half dollar with an s mint mark that appears to be out of place, it is located just below the D in GOD and to the left of Presidents neckline. The vast major of 1776-1976 Kennedy clad half dollar have the mint mark below Presidents neckline and centered above...

My in-laws have this coin that they think is rare, so I'd like to know if it really is... The coin/ medal is larger than a quarter and is copper (?) clad... it has what appears to be the liberty bell on one side and states "United States of America- Bicentennial"... On the other side it states...

It is a silver dollar. On the back is the liberty bell with two stars

Hi! I'm looking for the possible collectible monetary value of 1776 - 1976, "D" mint mark uncirculated set of coins. They're still in the soft plastic wrapper from the mint. I would also like to know if I should be taking them out of that wrapper or not and storing them in some other way....
