But it is likely that you had something incorrectly listed in the "About this item" section. Did you create the listing entirely yourself or did you use a "sell one like this" template from another seller's listing. Either way, you have make sure every data point is correct or the card (which is clearly real) will still fail to pass eBay authentication. I would look through the particulars of the listing. It is likely that something, even seemingly irrelevant, is incorrectly noted.
