As you know I am selling some of my MTG collection (the oldest and the bestest stuff) to finance photographic gear.  I spent awhile researching prices so my stuff could be competitively priced–which was a little challenging because for some of the hotter stuff (the Unlimited and Arabian Nights sets) there hasn't been an auction on ebay for months on these items.  I finally figured out why.  Potential sellers are waiting for a price to beat.  After months with very little in the way of complete sets of Unlimited/Arabians, within a day of me listing my sets for auction, a bunch of other sellers crawled out of the woodwork and listed their sets for auction, all undercutting me by small amounts (typically about $50), or by setting high reserves and no minimum bid.  Since all these auctions are now running simultaneously, there is suddenly a lot of options for the prospective buyer, and since mine is ending before the others, the lower-priced auctions are going to see all the action.

So at this point I don't expect the Arabians or Unlimited sets to sell, and now I'm going to have to sit around like the other campers and wait for some other seller to come along so I can undercut him or her.

Pain in the ass.  The amusing thing is, sets this rare sell so infrequently that if a seller waited until my auction was over, he'd end up doing better than he would if they all try to sell at the same time and undercut each other.  Oh well… I guess the buyers win!
