T206 Moeller (Raw) with a Pencil Mark

[Leon]

I went to a local show yesterday, in Grapevine Texas, and picked up this beauty along with 20 other raw, common T206s. Not pristine but just nice looking cards. Of course none will grade above a 4 (or so) so this isn't going to be a big time pick up. That said, we have had discussions about different alterations blah blah blah. So why not a real world one we can discuss? This card has a pencil mark on back. I have a trusty Mars plastic eraser on my desk that I will probably use on it. It isn't a crime to do that, unless you say you didn't, although some consider it sacrilegious and I can see that point too. So getting the "it is fraud" discussion out of the way, is it ok to erase this mark? If I then submit it what happens if it later gets found with the mark and then, graded, it doesn't have it? And actually, for sake of discussion, that mark might hold it back up to 2 grades!! I could see it being a 1 to 1.5 with the mark and a 2.5?-3 without it. Yikes. Real world issue on a 35 buck card.
