Had a board member ask me today if certain cards were known, so figured I would update and bump this thread. I know a number of blank backs have come up for sale in the past year or so and I haven't updated them so if anyone has additions to add to/remove from the lists please let me know.

I don't see the Bender white cap blank back listed on your original post.

Confirmed picture in Leons post #64 of this thread.

And yes, I would love to overpay somebody for that card if they own it.

EDIT: NVM, I've been made aware that is a T216 blank back (I'd still like to buy it though).

Phil, yes, that is my understanding as well and the reason I did not include it. This thread gives some clues on the differences between E92 and T216 blank backs: https://www.net54baseball.com/showthread.php?t=198503
