Kevin - agree 100% about both Joe and SGC. As I have stated, my post was not meant to suggest that they were involved in any wrongdoing. If that is what can be inferred from it, I apologize.
I would agree with you about it possibly being a similar card if it were a T206, but there aren't too many Mothers Bread Plank's out there. I can literally picture the moment I tried to slide the card into a top loader and put that little fold in the bottom right corner. If there are two Mother's bread Plank's out there like that, I will eat my hat.
Either way - I am sure it will be resolved one way or another, and I look forward to buying from this dealer and using SGC's services in the future.
