Card has great eye appeal. Both PSA and SGC do a good job. I would guess there is a technicality keeping that in PSA 2 holder. It was graded before the change to the .5 system so now PSA may bump it to 2.5. Pre war cards look mighty nice in SGC holders. I think it would be a good idea to cross it over. I can't imagine the grade going down and if it stays the same you've lost nothing, perhaps gained by having it in an SGC holder.
