Sometimes it helps when the OP points out whatever it is he/she sees so that the board knows what to look for. With that said, the only one I looked at - the 60-D - shows damage.
Ok point well taken ,, I thought it would be noticeable enough sorry I am mistaken.. I do think you are incorrect about 1960 D . take a second look.
@ coinman1234 Ok , I guess I didn't know they did lamination in 1942.. Do you know the process? I thought all copper was all cooper or 90 some % anyway..
It is unrelated to plating or anything. It has do with gas being trapped in the planchet, the gas creates impurities in the planchet making the coin look like that.
Ok @ coinman1234 Very nice pic TY, That being said all post 1982 penny's that have any erosion on them or bubbling are most likely from plating not gasses? Or maybe both? Charles
If the anomalies in question are those located just to the right of the 6, and to the distant right of the mintmark, they appear to be gouges of some sort, but are most certainly damage.
From the first picture down I'm seeing a struck-through, a lamination, then machine damage on the '60-D, no other errors.
Post 1982 pennies are mainly due to bubbles under the plating, they are not the same as Lamination, they are just plating problems. In the 1980's zinc cents were not plated that well so you see some plating problems.
