2013 ASE Hairlines

I have a friend that has let me look threw 3 rolls of 2013 ASE's to cherry pick high grades. None of them are that great. However I experienced some things I didn't expect and am trying desperately to learn more about grading, so I figured I would post the question.

All three rolls have hairlines on every coin. Each roll has it's own distinct pattern, but they are all in the right field. The hairlines are exactly the same one every coin within the roll. So am I right in thinking that this was in the die? And that every coin in the roll came from the same die?

The real question is how I should take these hairlines into consideration when assigning a grade. The hairlines are plentiful on each coin but are very light. They are not visible with out magnification. They are so light that I think they could be missed by someone giving the coin a quick once over with magnification. I have NGC slabbed ms69 ASE's that are worse than these. They do not show up on pictures otherwise I would post a few.

Going by the ANA grading standards as I understand them 70, 69, and 68 do not allow for any hairlines so we can count them out. 67 allows for 2 under magnification and 66 allows for a few under magnification. How many is a few? I have always taken this as 3 or 4. Then all of a sudden 65 allows for them to be seen without magnification. 65 seems to be the grade to give them but it just seems to low for how these coins really look.

Sorry for asking a question in the form of a book, and I hope that I have made sense at this late hour. I realize that a ASE has no difference in value between middle MS grades, but it isn't about the value. I am really just trying to understand the grading process better. Thank you for your help.
