longshot 1952 topps question

BasherBoy

I have an odd request, I don't know if anybody could help me out. I'm not collecting the set, I'm mostly just a team collector (Indians) I need a 52 Topps Bob Kennedy Black Back to finish my team set. I have one, but it is slabbed without the black back notation so it won't go in the proper slot on my registry. I don't really submit to psa (have once) I just wondered if anybody working on a 52 basic set might have one slabbed correctly that they might trade for mine. I would throw in a few $ or send a card or two for your trouble. I know it's a longshot, but thought I'd ask. Scans below of the card I have.
