I just saw on ebay lots of copies of the 26 volumes being sold with the lowest asking price being $2500. A set signed by 3 of the commissioners was asking $6500. I don't know why anyone would shell out thousands of dollars for something that is available online for free. They are also available on DVDs for reasonable prices. Maybe the sets have some collectible value but with so many in circulation, I doubt they have that much value as collectibles. Of course, if I could find a Carcano the same model as Oswald's, I'd probably be willing to shell out a several hundred dollars for it, so I sort of understand people wanting the original printed volumes.
