About six months ago I sold a raw (but not altered) beater E93 Wagner here on the BST. I accepted a price I was satisfied with and would have broken even had I paid for grading/shipping fees. That card was sold within a week, so I know it remained ungraded.
Later on, I sold a 40-count stack of ungraded E90-1 -- major HOFers and stars and commons -- here on the BST. Soon after, a few of them were put up for auction, raw, once again on the BST.
The remainder of that original sold stack are now appearing in the current Sterling auction (if you know my former cards, they are the ones with the holes in them
). And still, they are ungraded.
Except for certain cards I am not for or against grading, and apparently neither are the buyers or the auction house. Hope this helps.
