Chuck W.,
Thanks for posting the Wagner. I admit that card and the Young are now the only ones I've ever seen like that. I literally looked through thousands of scans of PSA T206 to check, and those remain the only 2 I've ever seen like that.
As I mentioned before, I have no problem with the # on the flip. That is not a warning sign to me because I've seen it many times, but always with "T206" and not "1911".
An example of that is on the red Cobb in this lot from last year's REA - it has the # and the T206 identification:

As you can also see from that lot, the Johnson - a very old PSA graded card - also identifies by T206 only.
It is a mystery to me why for some period (which must have been very, very short) PSA put 1911 on these flips and not T206

.
Anyways, thanks very much for adding an important piece to the discussion.
Cheers,
Blair
