I noticed this spot on Lincoln's forehead. It looks like delamination to me, as the material in that area is higher than the rest of his forehead (tried to take a photo of the material height difference).Still learning about errors so just looking for and appreciate additional input.

I was going through some change and I came across this 1988 dime. I noticed there was something the light hit between Liberty and Roosevelt's face. Any idea what this might be? Any help appreciated!
