Nearly all (about 400) of Apple's Developer CDs are being auctioned off over at eBay. The bidding has started at $799 and is restricted only to those who can prove that they are an "Apple Authorized and Seeded Developer".

"EVERY CD Apple has released to developers since (& including) volume II (Phil & Dave's excellent CD) (There was no "volume I"). Every OS; every reference library, Tools, Seed CDs, OpenDoc (remember?) and so on."
