When it comes to collectibles, value is based on the relationship between supply and demand. In simpler terms, that means you'll get the big bucks only when you have something really rare that lots of people want to own. That's why it's pretty amusing to see someone trying to auction some cheap 1980's era Microsoft sunglasses on Ebay for the price of a house. The seller claims that these were made in very limited numbers, and that this is probably the only pair still around. So they are really rare, but unless Bill G himself has some weird nostalgic memories of this promotional item, I can't see anyone coughing up this sort of money. Lower the reserve to $10, and perhaps I will put it on my watch list.
