My best Lamination error I've found so far

Or should I be calling it a part missing clad?

Also do you think the eye thing is PMD?

Certainly not a lamination. Looks more like a stain of some sort.
The eye looks like it has some gunk in it.

Just seeing a stain Just a damaged coin. No errors. Worth 25 cents.

I don't see this as a lamination. I think it's some form of staining.

Thank you for your inputs, appreciated it and guided to me a conclusion. I have acetone bathed it for a day so it's not a glue or anything similar. What was throwing me was the cracks complimenting the damage, however laminate errors are in straight lines and a clad layer error would make it weigh less.

My conclusion is this coin suffers from post-mint environmental acid corrosion that has deeply eaten into the copper-nickel alloy, leaving behind green verdigris crust and corrosion, revealing the under-surface alloy, which has induced stress corrosion cracking (SCC). All of which is PMD.
