[CardPadre]

I think it has too much card missing to be a 1…probably have to call that more than small pieces gone. But I could see it in an Authentic without the trimming designation maybe.

With all the corner areas gone, makes me think it was either pinned up on a board at the corners or was possibly cut like kids do and then suffered further wear.

But it is damaged really unusually, I can’t say with any real certainty what brought it to that condition. But a straight Authentic would probably be as good as you could get. And you might be able to get that elsewhere if SGC won’t change their opinion.
