Based on some of the comments in that video, he spent 15 k on that pack? GAI "graded"?
Compare that to the '52 T Christmas rack pack that just sold for $795 on ebay, and it even had a high # showing on the front and looked like maybe the cards might be in pretty good shape. I wonder if it's possible to slide the cards apart and see in those rack packs (like you could with some issues in the '80s).
Regardless, looks like they usually sell between 500 and 1000 bucks. Obviously a neon sign that you'll have a better chance of pulling a big card out of great aunt dorothy's old denture case
