"Unsearched" rolls are one of the biggest scams on eBay in my opinion. I am amazed how many people fall for it and how many people overpay by ridiculous amounts if there is some "special" coin on the end. You'd be better off spending that money on lottery tickets. At least the odds aren't 0.
Ow, that hurts. I actually have a bid in on one of those because I just happen to need that particular coin for one of my Whitman books. Of course my bid is not much higher (ok a little, but not much) than that particular coin is worth to me, and I will probably be left in the dust over the next couple of days. Ce la vie.
I've bought a roll or two off eBay just to fill common holes in my Whitman books. I've never gotten anything special, but I didn't expect it either.
