Early into the auction I bid on a 52 topps Mantle in SGC 30 with a max bid. I was then outbid and then this past week, I rebid, and then was outbid again and let the card go. Then this morning I received an invoice that I had won the card. I never received a bid retraction email at any point. I am now wondering how this could happen and about the validity of the other bids on this lot.
Is there anyway to get proof of what happened and if it was isolated?
