occluded gas bubles usually only occur on solid alloy coins...but that is the only other guess I can come up with other than a lamination

If it were stuck in debris,wouldnt you be able to see the edges or complete outline of the fragment? This appears to be blended in so well to the surface that I wouldnt personally say it is simply a strike thru...just my opinion

Certainly seems lam-like with the lip peeling away at the rim near IGWT.

Lamination that just didn't crack along the surface in many places. I like it.

Excellent intuition, paid off well. First for me as well.

What is the anomaly on the rim below the date? It seems to be in line with the main part. Any images of that part of the edge?
I'm wondering if this could be something (grease? oil? liquid?) that got between the layers and kept them from bonding.

Still part of the same issue. It would be nice to see if it folds over on the reeds? If so and it covers the copper layer, that would be concluding proof that is is a struck through part separate partial cladding on the area. Good thought though? Can wait to hear what the answer is to my question.

The obverse clad layer is separating internally along the horizontal plane. Basically we're looking at a lamination error restricted to the surface of the clad layer.

The physical effect of this it is: When you strike, the forces are from the center to outside. If you strike trough debris, are mean you will have high percentage of vibration on that part of the object. In our case is a clad coin so the vibrations which are internal to the material could go to the exfoliation of the clad foil.
Maybe to short explanation and to physically
PS For numismatic I will say struck through debris and exfoliation.
