Looks like photo#1 and #4 have a die clash line at the back of Abe's head. And just so you know, "Die Polishing" removes lines/scratches from the face of a coin die. Die cleaning increases the amount of scratches on the surface of a coin die, which in turn are transferred to the surface of the coins they strike.
@Paddy54 That first coin has so many die polishing lines. I can see now how you might have thought that. That is the memorial clash. I will take some better photos. I have been on the hunt for an un abraded example in the bag. I haven't found it yet.
1 is the bottom of the Memorial. 2 is the top cornice area of the Memorial If you look closely there are some of the pillars still evident above RTY. Also there is evidence if the Memorial in front of ABE. I just can't capture it.
