Unfortunately I don't have much of an update here.
Last I heard from the seller someone in PA, a dealer I presume, had removed the cards from the album and nearly doubled his offer (to at least $15k so he said) once the cards were removed.
They must've came out without damage and/or had some rare backs. They do seem to average EX or better with clean fronts.
All I've got are these low quality pictures of the fronts:

The seller referenced a list of information on the cards post-removal, and was going to share it with me, but never did despite several follow-ups.
If any of you know any dealers near Telford, PA maybe we could find out more through them. It would be great to know about the backs.
