Aaron M.The seller, in your instance, was probably inclined to not bring attention to his sales because his sales history on E-Bay were so clear cut.
Above in this thread a poster linked to two of his transaction for a Mickey Mantle card. In the earlier transaction he states openly and clearly in his description that the cards he was selling were rejected by PSA as trimmed or otherwise altered.
Obviously unhappy with the prices he was getting for being honest, he had the trimmed cards graded by PRO and then offered them up again with not a mention of the card's having been trimmed or rejected by PSA as such. Instant better sales price via fraud for him. A worthless card for the unfortunate buyer.
So don't think the seller was doing you a favor by agreeing to void the transaction. You had more leverage than you think. (You could have reported him to E-Bay or contacted other winners of his auctions and advised them on what exactly they had purchased.)
