>>6416042It's hard to say as there isn't a developed aftermarket like for Lego, and much less demand it seems. I've seen several collections of value going for practically peanuts on kijiji (bought a lot for $15 Cdn that was easily over a hundred bucks worth originally) while ebay tends to have shall we say "collector prices" on the regular.
I know what I'd like to get for pic related if I were ever to part with it, could roughly estimate value based on where each fig came from... but I know I'd be lucky to get a fraction of that.
