2017 P Lincoln Shield Cent Die Chip?

I was looking for the doubling on the Y in Liberty, being the upper part of the Y,left side is thicker than the right side, I noticed what looked like a die chip on top of the Y left hand side. After blowing it up I noticed on the right side of the Y, what appears to be a hit from PMD. After looking at both of these I come to the conclusion that the Y on the right hand side took a hit and pushed the metal up to the
left hand side of the Y. I mean that piece of metal fits perfectly where it took a hit. What other chances of something like that happen, probably more than I realized. But that is so cool, yes little things excite me LOL. Which brings me to ask you, is the word Liberty extra thickness? Or is that deterioration on the die? Moving on, how about under his eye? Zinc bubble that popped? On the reverse the last banner on the left side of the shield, bottom rt looks a little chewed up. Could that be from a Grease filed die? Thank you in advance
