Your photos are inconclusive. Is the area you are trying to show near the rim of the obverse by the LIBERTY? If you over magnify any coin, you can start to see things that are mostly pareidolia. Could be die chips, but being a Zincoln, it is probably just small blisters, but I can't tell from your photos. Good luck.
Sorry guys have been busy here are some better pics hope this helps. The arrow looking things are like a die clash and I am certain it's not blisters or damage
That's definitely not a clash of any kind. It would have to be something from the Reverse Die and there are no triangles on there. Do you know what a clash is? It's when there is no blank planchet present in the chamber to be struck by both dies so they strike each other. That will cause a slight impression of each die on each other. So when the planchets are struck you will see a slight image from each side. Here is an overlay of a Lincoln Memorial Cent..
Those triangles look like a series of hits, probably from other coins. Nothing like a clash as stated above.
I do know what a die clash is I didn't say it was a die clash I said it's like a die clash it is not damage I wish I had a better camera so you could see what I see it's not a series of hits from other coins
