Fascinating stuff.
My one T3 is in a screwdown I made myself from hardware store plastic. So far it's held up fine. The card was pretty well trashed when I bought it.
Oddly, some cards I had in larger screwdowns came out ok, despite the plastic showing some weird damage. The holders look almost melted, but haven't been around any heat.
I remember the Baldwin sheets. And I think the MVP sheets too. As well as the othe early PVC sheets, that I've got a bunch of. They never damaged my cards, but they did stick together after a while.
Interesting that it was a regional thing. I always just assumed the sheets were sold nationally.
I had some doubts about the grading holders, and still do. But they've got a few years into it without the problems I'd expected so they're probably ok.
Keep it coming guys, to me this is a fascinating look at an aspect of the hobby that hardly ever gets a mention.
