An auction concludes and a card worth $5000 sells for $1200 because it was miscategorized. Somebody puts it on the board an hour after it closes expressing his amazement that it sold so cheaply. Now that everyone knows about it, some unscrupulous person contacts the seller and offers him twice the selling price for it. It's going to get sticky.
