The book sells for $125 and up when you find it on ABE or Bibliofind (of course, there are exceptions and a bargain can be had.) That's nothing compared to "Phenix City, The Wickedest City in America" at several hundred for the first and only edition or "To Drop A Dime," which is one of the priciest organized crime book out there at $175 to $500 a copy in paperback!
It's a question of whether it is worth the price to someone who doesn't have a copy. I've heard some folks have paid a lot for more a little round piece of clay! :)
Cheers,
