I'm 99% sure this is no good.
1. Blank back. Everyone I've ever seen has printing on the back.
2. Not in the PSA Holder - looks like it was sent in and sent back due to questionable authenticty.
3. Corners cut, never seen one like that.
4. Could be a Proof, but PSA grades Proofs and note them as such and would have here if they thought that.
Anyone else have any concerns with it?
