As I was looking at these coins and some 64 Kennedys, I noticed that 1 of the Franklins looked smaller or either 1 looked flatter and bigger so I weighed them. One 54 weighed 12.5 grams while the other weighed 12.2. The 56 weighed 12. Is this typical that coins can vary in weight?
Before I sell, are these coins considered worn..The one 1954 is very prominent in the features (high on both sides).
Thanks again!
