AbeBooks' sends me a genre related email list every once in a while.  I was amused at this recent topic.  Here are the top prices paid for SF & F books in 2006.

* Book images are not of those that actually sold.

1. 1984

George Orwell

First edition, first impression of this 1949 dystopian classic. There were two versions of the dustjacket issued, one green and one red. There is no priority between them. Copies in this condition are deeply uncommon. The jacket has a nick or two at the odd corner and a trace of rub but is one of the best copies. Sold for $8,258.40

2. (tied) Neuromancer (2), Count Zero, Mona Lisa Overdrive

William Gibson

Three first edition Gollancz hard covers and one Ace paperback of Neuromancer. The Gollancz copies are in fine, unread condition in fine unclipped dust jackets, and all are signed by Gibson. Sold for $7,500
