I have a hard time feeling the poly bags to. Ale my sets so I've been opening them to make my sets and selling or trading the doubles. Once I complete a set I usually put it in a frame and never touch the figures again. So my question is do you think it hurts the overall value by doing it this way and if it does how do people make their sets complete without being 100% sure that they have all the different figs and not multiples of some? And information is great appreciated, I have a nice size collection so far but I just started collecting about 6 weeks ago.
