I have a beautiful '51 Bowman Mantle that was in an old GAI 5 container (purchased on here many many years ago in fact). I tried crossing it to PSA in the GAI slab with a minimum grade of 4, and it would not cross (minimum grade not met). I then decided to crack it and submit it raw to PSA, and it came back a 5.
