martindlIn this case it doesn't appear that the seller knew what they had, but as seller on Ebay i've lost out twice by letting an auction run, albeit on non cards.
In both instances I knew what i had and knew the relative value. I received a buy-it-now request for $350 within an hour of putting a listing for a record up. Market value for the record was about $300. I was tempted but let the auction run. It sold for $122, and not to the person offering the BIN. Same thing with an old colorized-photo. Value was about $200. I had multiple offers, the highest being $175 and it sold for a hair over $100. I made money on both, but left money on the table.
I do understand why sellers will take the money and run. Its got to be especially difficult if they're offered a large sum on something they think has modest value. Course, if that happened to me, i'd likely pull it and start researching like crazy.
May thats what happened here.
