But which will be "RARER" based on print run,book cover variations (1st editions only?) Let's say 10,000 first print run that's only 2,500 of each cover (we know that Gwendy's Button Box was in a 4th printing in no time at all),dust jacket variation (WHSiith) & postage to the states? The only rare ones here will be the ones signed on the tour. (Not counting S/L editions)
