That's a great question.

If we are going to start placing high values on known altered cards (and obviously this is the case based on this Mantle sale), then it's important that the list of alterations follows the card each time it is sold.

Alterations like those done on the Mantle are similar to what is accepted in the realms of movie posters, rare books, comic books, and paintings, just to name a few. Those hobbies also use the protocol of full disclosure when selling an altered item.

I hope I'm wrong, but I'd agree with Matt that the extent of alterations on that card would hopefully never get a numerical grade from PSA or SGC.
