Not bag toning. It looks like it was in an old board or folder that only shows 1 side. Looks to have been subjected to many fingers and other contaminates on the side that was exposed.
I see that toning on NTC slabs all the time....quite fugly. And MS-68? The reverse is killer, but now way that flat strike on the front makes MS-68...maybe 64-65 on a good day.

Definitely not textile toning - palm/finger prints most likely, and as for the toning - it looks more like album toning than bag toning.
Now I know what bag toning would typically look like.
I have no idea how they came up with a MS68 grade on that.
That is a thumbprint creating the toning "patterns". (well, actually, thumbprintS).
Don't buy NTC...if you do, do it sightseen, strong return policy, and lower grades.
I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment
