I have many of the old figures. In loose condition, without the accessories, 10 bucks is about the going price (depending on the character of course). When you start getting figures in the boxes, with the guns, etc., the price can rise rather quickly. I probably have 200 loose figures, and probably 25 in boxes. I also have countless vehicles, collector's boxes, etc.
It seemed as if interest/value of the figures went down after this new trilogy came out. Hopefully, interest didn't die off completely, and when it comes time for me to retire, I can sell these, and make up for the Social Security money being gone...Damn old people!
