You mention that LIBERTY is the area of focus, yet you provide a picture taken at an angle of Lincoln's face and the date. I don't see anything out of the ordinary.
very hard to see but above the date i can see where the t and the y are pritty good on the coin with a 30x glass. not real bold , But I think thats what i see.. I will ty to post another pic..
Your coin looks to have quite a bit of lamination on it. This may be what you are seeing but a better photo may help.
I don't see anything unusual on the coin. I'd say what you are seeing is most likely coincidental damage.
