I had to sell a large collection of props and set pieces when Viacon/Paramount sued me for copyright infringement.
But as someone said: "hard to get, and what does it do? It sits in a display case for you to look at and show your friends--sure you may take it out now and then, go to a convention, etc, but bottom line is --it just sits."
So true, and in my case it was either hidden away in boxes or what I did show was subject to stealing (a couple of minor thinks was stolen) or caused bad feels with some of my friends when I would not give them some of them.
So as I do regret selling this stuff off: They did keep us alive to regroup and rebuild.
