That effect is not the effect of die erosion or circulating wear. It has been subjected to some abnormal abrasive action, such as being run through a rock tumbler. Normal wear looks nothing like that.

I added a pic of the other side of the penny. If it was in a Tumblr I believe the other side would be all messed up. I don't know how to take a really good pic thru the microscope with my phone.

It looks like something is wrong with this 1961 D penny. Is it build up of material when it was struck? Is that why the D is filled in? Or was it struck multiple times? I'm confused. Please help to clarify thank you.
