eBay works kinda like this: you minimize your investment time and that is gonna cost some (beyond the cost of the auction, shipping, etc.) When you have really rare things (and I think that these are pretty rare) the equation goes out the window, and you can expect a better return.

Because these marks are sooo rare, they might not get all of the attention that they need. It depends on who is looking at the time that they are up, who has the money, and who wants that particular bike. Clearly more that $500, though. You could part 'em out and make more than that on each. The Chiorda has additional history (I read about the show bikes somewhere on the web a while ago), and that should contribute to a good return. eBay can be disappointing, though. I know it is not the best way to get bids, but I'd put my minimum reserve on 'em, in case Wilma clears out all of the collectors in the southeast, for instance...
