Hoping you can share some PSA holder knowledge

[chadeast]

Hi all. I am planning to send in a few submissions to PSA after a 12 year hiatus, thanks to the Oversized Card grading special. The special says that items accepted include "Supersized, T3, & Jumbo cards". And there is a list of exclusions. But the question I have, which it seems the PSA site does not address anywhere, is what card sets fall under the Supersized, T3, & Jumbo categories? Is there a list somewhere on the PSA site or are we supposed to submit and just hope that we're right?

For example, do M101-2's fall under the Jumbo card category? I assume that T9's are part of the T3 category, but it would be nice to know for sure before I send any in. What about W600's, where do they fall in the PSA categories of card slabs? I have to believe that this is defined somewhere on the PSA site and that they don't leave submitters guessing, but I haven't spent time on the site in many years and I don't find their menu system very intuitive at all.

Thanks for your help!
