I think TPGs should continue to grade back damage accordingly regardless of issue, there are too many sellers that use nothing but the number on the slab as their description of the card.
I like the idea of having a separate grade for photo quality; however, do we really need the TPGs to tell us how nice the photo is? Photo quality seems obvious to me.
Anthony- Your Hellman is a beautiful card. If it were given a higher grade due to photo quality, it probably would have cost more. Would you really want that?
