Gene Roddenberry's Mac Plus Is Coming Up For Auction

Harry writes "In 1986, Apple unveiled one of the most popular Macintoshes ever, the Mac Plus. The company gave the first one (serial number #F4200NUM0001) to Star Trek's creator, Gene Roddenberry. And now this very Mac Plus will go up for auction at a Hollywood collectibles event on October 8th and 9th, complete with a letter of authenticity from Roddenberry's son. The estimated value is only $800-$1200, which seems reasonable enough, given its double historical significance." Any bets on how high the bidding will go?
