I have an unidentified substance on some of these cards. It reminds me of thick chalk. I think several cards were graded with this on them. I just tried scratching a very small portion of it off one of the ungraded cards just to see what would happen and it comes right off with no visible damage.
I know with pencil marks I was told not to touch them. I don't know about this stuff though. On some of the cards it covers 75% of the picture. This is the card I played with. Any thoughts?
