Ben and John hit the nail on the head. I agree wholeheartedly with both.
I have a PSA-holdered card I bought off BST that, it turns out, used to sit in an SGC A flip. I sent it into PSA under the guarantee and they affirmed their opinion of a numerical grade; it now sits in a new holder but with the old/original PSA cert#. While I am skeptical, it’s all I can do; and, theoretically, they are the experts
