If someone listed some cards for auction on eBay running from one Sunday night to the next, and let's say they were pre-war cards from obscure sets, and that seller forgot to specify the era when he listed them, but then the cards received bids so the seller was no longer able to fix that, and let's say he didn't realize this until last night when he was doing his own search for pre-war card auctions in progress and didn't see any of his own cards, what percentage of the potential bidder attention and what percentage of closing price do you suppose that person would be missing out on?
"Asking for a friend" as the kids say.
