Hi
the best way is to upload pictures of the figures and any accessories/ weapons on the valuation section of the forum.
you will then get some benchmark valuations for your figures, which you could then put up on the sales section of this forum
lots of people have sold there childhood figures, then regretted it, so first make sure you want to let them go, then get the valuations and take it from there
plenty of the guys will help with values on here
Ask expert collectors for advice on pricing items.
