Under Authentication section
"Steve Hart, Owner of Baseball Card Exchange, is the hobby's foremost authenticator of unopened vintage wax packs and boxes. He is the only pack authenticator PSA has ever had. Wax packs, also called unopened packs, are collectible cards still in their original packaging."
I'm not sure if this is just referring to sports card packs though but if you go to about the 30 minute mark of Rattle's latest video he shows examples of fake packs even a 1st Edition Base that was cracked and opened and had all unlimited cards in it that looked like it was graded some time ago.

Unless there is a real Pokemon expert when they open this case I'm calling BS on all of it if there are 1st Edition boxes in it. I don't trust any of the guys involved in this.
