I've started yearning for my childhood and have been rummaging through my old toys and wanted to see what you guys might estimate some of the fair market value for some of these items are. I've put my estimates based on eBay prices but wanted to get the opinion of experts.
I know most of these are in pretty poor condition since I actually played with all of these as a kid. So I imagine many are worth next to nothing, but who knows! These are all originals not reissues as far as I can tell.
Fortress Maximus (Guessing $100-$200?) - missing basically every single piece possible aside from the head. Although the head doesn't have a his headmaster. No yellowing but I haven't cleaned it and most of the stickers are missing which doesn't seem to be an issue since there are tons of reissue stickers available, I think?

Pretenders
Bumblebee ($25?) - Shell and inner Bumblebee. No other accessories found
Longtooth with inner robot ($20?) - Inner robot has no hood or red piece. No other accessories currently found

Purple space ship. I think a Decepticon? Right leg missing too.

Action Masters
Grimlock ($10?) - While doing research, I saw that he comes with some kind of gun and I'm 99% sure I saw that somewhere today.
Prowl ($5?)
Starscream

Small combiners of some sort. Only torso and both arms.

Random small vehicles

Random parts that look like two Optimus Prime trailers of some sort


Non-TF
1997 Trendsetters Voltron Die Cast with Gold weapons ($100ish?) - Complete with very little play/wear. I think only the Black Lion has wear on his legs where the legs join.

Thanks in advance for any help you all can provide. If any are worthwhile I'll create a WTB/WTT thread after I get enough info on these guys.
