Anyone seen these marks on a 1967 coin before. I somewhat see these on the stock photo for the SMS on the NGC website listing, but can't be 100%. I have 3 coins with these 3 marks. Thank you in advanced for the help. New smember
Welcome to CT @Mister J. Might be part of the Lincoln Memorial from a clash. Looks like it may have been polished out. Next time show the full coin as well as the area of interest.
The polishing was done by a mint employee to remove the clash marks. I would keep it in a flip and mark it as clash mark.
Looks like a die clash to me as well. It would be from the memorial. Put it in a flip to protect it. Welcome to CT.
