OK, this one seems a bit "scammy" to me. Tell me if you agree.
A PGX AF 15 "Back Cover Only" on ebay. It already has 10 bidders and the bidding is over $100 with a day left.
Correct me if I'm wrong but there's no way to know for sure if that's an AF15 back cover. It could be, but it could also be a Kid Colt 106, or a TTA 35 or 36, or a TOS 33 or 34. Right?
Has CGC ever slabbed an AF15 back cover? It would be one thing if the spine partially wrapped around to a piece of the front cover, but this one goes no further than a tiny piece of the black line that many comics have going down the spine
