Well, the Adlib Gold is, in fact, relatively rare, so I guess it might be worth that much, but only to the most enthusiast sound card collector. There's nothing in the Adlib Gold that other cards from it's era don't have or surpass (except for the surround module, which I didn't see the seller offer), which is one of the reasons it failed so miserably - thereby causing Adlib, Inc. to bankrupt.
Had the AdLib Gold been released in the 4th quarter of 1991, as was originally planned, it would have had a roughly six-month jump on the PAS16, and nearly a year on the first SB16. Its competition, at that time, would have been the original PAS, and the original SoundBlaster Pro, both of which it trounces.
I don't consider it a failure, if only for the RL2 demonstration files that AdLib produced for it.
