Thoughts on this scenario?
 

Any thoughts on value or what strategy to use on this card? Would PSA give it a (mk).? Never ran into this on a nicer card.

Thanks!

Peter Sycks is selling an authentic 1951 Bowman Mantle with a fake signature on the board's B/S/T, and he said:

"PSA won't grade just the card, they need to authenticate both. They won't slab it with only the card being authentic."

Hope Peter is okay with me posting this. David Maupin

Thanks, that's helpful. That's a nice 51 Mantle.
