Can the experts tell what's going on with this Mantle?

Irv, I'm sure the seller already tried SGC. No one is going to buy this and then have much luck getting it into a number grade holder. I can't say what the seller's motive was in saying they couldn't detect what was altered. Maybe they couldn't determine what was wrong. I know that I've encountered sellers of Authentic cards that genuinely couldn't detect what had been done (as others said, it can be hard once it is in the older).
