Is this a legit 1/1? I am not familiar with this seller and this is not an endorsement or otherwise. They do have a 99.9 rating w/ 2000+ auctions. which isn't perfect, but it is pretty good.
Granted this auction ended at a bad time on the day after Christmas, but shouldn't any Jeter 1/1 even if it is part of a huge list of cards in milestones generate at least 1 bid. This particular card also represent number 1 in the series which one would think would give it some added cache.
For less than 5 bucks including shipping somebody could have had a Derek Jeter 1/1 and not one person bid. Have 1/1 cards declined in significance that much?
