Was just asked a couple of questions and thought I would clarify it here too.
The back of the penny below the one with Kennedy on it is where a chunk of another penny was stuck to the die. It is very well adhered to the other penny and the penny shows litle detail.
This is not entire collection. This is just the neater coins and the older ones.
The remainder of what is on the desk is just silver, no clad in the pictures.
