Hello again-
Researching these items has been fun, but now I'm thinking I should have just posted to this forum in the beginning!  As it is, I ended up with most of my questions answered, except the following.  Any interest in discussing the following:

-'Gems for Death' by The Companions (mint, basically never opened)
-TSR Module G2 (The Glacial Rift of the Frost Giant Jarl) very good folder, mint interior
-JG Dark Tower first ed (well-read, but otherwise very good)

Also, I have a 1979 Villians and Vigilantes rule book I can't decide where to take.  I actually e-mailed the authors (they have been in the news lately), but I haven't heard back from them.

(for other things please see my recent classified, and also I'll post some Traveller, Fantasy Trip, and a few other things when I have time)

Gems for Death is a good module - probably the rarest one of the Companions line (but maybe not quite the most valuable).  In mint condition, $50-$75, probably higher a few years back.

G2 really depends on the print - typical shape would be $15-$25, a 1st print would bring you more.  Maybe tougher to sell without G1 and G3?

Dark Tower - lots of Judges Guild experts to answer this but the webpage estimates it at $29

V&V doesn't ever seem to sell for much it seems but maybe a 1st edition is rare?  I think I've seen a number of 2nds but maybe not so many 1sts.

I put it on eBay, and got a $38 sell it now. I might have been able to get more for it, but I don't see much reason for regret.  I'm happy enough that V&V did well after all these years.
