As an example - desert shield 1991s. I sent a few true commons that are now just permanently stuck in that category. Not worth grading and not worth shipping home.
Funny thing is a few of my batch did get listed without the flag. Maybe three out of 12.
I've been hampered by this as well. I think it started when they started submitting cards to CGC. Somewhere there's a specific list of cards which CGC doesn't grade, and that this somehow translated into a list of cards COMC won't accept anymore.
There are plenty of examples from some of these sets which appear to be grandfathered into the system. They'll still sell the ones on the site, but they won't take new ones unless they're "authenticated".
