Came across this while out of town. Sorry for the quality, I had to use my phone. Maybe I should start traveling with my coin equipment. I believe that this is a lamination error. It's not that noticeable on Lincoln's head but definitely to the right of his head.
To @potty dollar 1878 And the rest of the gang : Is it delamination or Lamination Error ? I see it used both ways according to Lamination Cracks (error-ref.com)
By the pictures to me it looked like the flake of metal fell off which then would make it a de-lamination.
@potty dollar 1878 , @SensibleSal66 Un-retained lamination is the term I believe you are hunting for.
Why do they have to have 100 different meanings!!Welcome to the coin world i guess.Really?it looks detached to me but ok then.
Looks like a lamination error. The main thing you first see is the detached area but look above Lincoln’s hairline. That’s an attached lamination. Nice find.
