Thanks very much for the replies. The idea is very much to sell to a collector and not a dealer, and I know there aren't a lot of people with interest but my figuring is that there's got to be some. You need someone with cash and an interest but who hasn't necessarily dedicated themselves already. That's why I posted on Neshek's board . . . and why if I could find Brad Lidge. The thought had also occurred that the Astros themselves might be interested, again because of the historical value. I actually sent Mike Acosta an email but no word from that direction either.
Anyway, all replies are appreciated, thanks! and I will continue to monitor.

You might still want to consider contacting card shops and dealers in the Houston area. They might be able to put you in contact with an Astros collector that could be interested.
