One of my favorite cards, and my old Babe Ruth card, is this sweet 1948 Leaf card that has been graded a BGS 5.5. I think it has an easy shot at a PSA 5 with an outside shot at a PSA 6. People don’t love BGS for vintage but I think if you find a classic card in a BGS slab, it can represent a buying opportunity. I have very little desire to try to cross this though. It’s not worth the cost and I’m happy with the current slab (if I did anything, id move it to a BGS slab that is silver rather than the paper just for aesthetic reasons).
