I don't plan on selling this card, but I have to ask about WTH SGC is thinking.
I get that the surface defects are causing the card to be downgraded, but given the centering and the crisp edges and corners it would seem to fall under their criteria for a 5:
80/20 or better centering, minor rounding or fuzzing of corners, roughness or chipping along edge (no layering), one VERY slight surface or "spider" crease may exist on one side of the card, gloss may be lost from surface with some scratching that does not detract from the aesthetics of the card.
Am I wrong here?
