Agree 100% with Tamrock. I'm seeing lots of 1 bid, very high sold prices on ebay on a variety if items that have me wondering. Kinda like the Olympics, I'm throwing out the high scores.
One that comes to mind - I was at a garage sale and a sealed, boxed Lego item was there. It was a robot and had an electronic downloadable "brain" that is used in some other Legos. I buy it for 5 dollars. And nearly have a heart attack when the first one on ebay sold listing came up at $10,000.00! One bid. I haven't sold it yet, but on further research, its maybe a $200 item.
Also, beware of fake AP watches. Saw an episode of that reality pawn shop show out of Detroit where the very tough owner got taken on an AP with box, papers, and all the bells and whistles. Which of course, reminds me of another story:
Last Saturday at a garage sale, there was a vintage Louis Vuitton pocketbook in its original vintage LV box, with cloth protective bag, with official numbered card registration and with the business card of the LV store where it was bought. All of it had that original, honest patina. The owner wanted $20.00 and as I pulled the money out she said (to her credit), "You realize that's a fake, don't you?" And it was. We both looked at it and she pointed out the various clues (especially stitching and un-eveness of the credit card slots. And I thought I was getting good at spotting fakes. Lesson learned.
