Wonderful to hear from the original owners of this collection. I won't be of much help as I am a noob where T cards are concerned.
I am so glad to hear that your cards will remain as they were intended to be...raw. Some call graded cards "entombed" and there is a reason for that. There is absolutely something special to the ability to hold the actual card in your hand (or at least being able to take it from its plastic holder if you ever wanted to....definitely good to keep them safe in those at least).
There are many here with decades of knowledge at your disposal.
I'm pretty much just sitting here at work drooling all over the keyboard. At the scans. Not your wife. Although...
