Has this been proven to be absolutely true and does PSA have documentation as such so they know if they are truely grading a tanback versus wonderbread? I am going to vote no on both accounts. I have a stack of Tied Wondbreads that have diecuts that are all over the place including matching pretty much both the patterns Rob shows here. If I am reminded to bring my wonderbreads to the next show, we can dissect them and see if we can come up with something solid.
I do know that all 2nd & 3rd series WB's had 1 asterisk except Tied, Gadzooka and Lavirus, so other than a potential die-cut pattern difference they would look just like series 1's.
I would be very surprised if PSA could tell a series 1 from a WB with these 3 titles, but I pay no attention to PSA so I'm not the right one to ask. I do my own grading! It's cheaper that way.
