Scott MosleyThere are a few SCG 88s and above in the set I just posted as an example.
I just posted it as an illustration that there are definitely still vintage cards out there in near mint condition which have not been slabbed (as I only recently had these done).
As far as it being mainstream, you'll have to tell me what sets qualify. I know E-98 is a pretty popular set among those of us that collect candy/caramel cards.
