They appear to be deep die scratches on the die. So much so that not just the fields are affected, but also part of the design. This is more of a die even, rather than trails. Most often trails are straight lines. Where as die scratches can be in any direction and curved. I would keep it safe for now. It might be something that the images are not showing at this point. When you get some better images you might re-post them on this same thread and I'll take another look. But that is what I'm seeing so far.
Hello all. Coop, I have tried and tried to get better pics, nothing. Started some reading and found this pic. It is a 1964 SMS Lincoln Cent with the same circular lines. In hand, these lines do not look like die polishing or scratch. Thank you for the help, Edward M.
