The images seem to indicate a blob of adhesive. A good soak in 100% acetone and see if it starts to loosen.
If it is into the coins surface then it would more likely be a detached lamination or a strike through.

Retained lamination is where the medal flake is still attached at the area the lamination is. Most of the time they fall off... or break off. But looking at your coin perhasp a strike though.? And ill tell you why...lamination when present on a coin can be one area on the surface, but more likely more than 1 spot.... more cracking than pitting ... on the coin.
This could be a greaser. I found a dime with grease still in place and when removed it left an incused area . check it out! Yours might be a little more extreme though.
Using the terms incused and raised in questioning is helpful from the start. Photos are often difficult to tell, and the OP, having the coin in hand, can tell easily.
