This appears to be a bi-level die crack - rather minor. Do you see what I see? Is it?

Also, the last I knew, there was no way to get rid of "milk spots" - has that changed? Is there a way?

It does appear to be a minuscule die crack. By "milk spots" do you mean the black dots?

Yes - and the other spots, too.

Those are carbon spots I think. The crack is pretty common.

Carbon spots only happen on copper cents. Probably ink spots on the plating.

Isn't the plating copper?

John has a point, doesn't he?

Please note that I am also referring to the spots which are more "filmy" and which I have seen called "milk spots" on the forum. It almost seems as if the dark spots are a further evolution they have taken - and may not be carbon spots at all.

I know that "milk spots" are identified with silver and that carbon spots are identified with copper. Here is a thread which explains all of that: http://goccf.com/t/171288

I am not yet convinced that the explanation accounts for the 2 types of spots I see on this coin - and many others.

Both types of spots are typically attributed to leftover residue from planchet rinse solution and neither type of spot can be removed without damage to the coin. However, silver and copper coins would have two different types of rinse solution. As far as I know, the US Mint is responsible for silver planchet prep while the Zincoln planchets are manufactured and prepared by Jarden Zinc.
