my rule of thumb is $2 for a “standard” theme fig, and $4 for a licensed fig or CMF. prices vary widely, but figs don’t sell as well as you’d think on bricklink.
Yeah, I’d agree with that – definitely YMMV with a big random mixed lot like this, there are a few licensed ones that’d possibly be worth more, but you’d have to look each one up. And yeah, figs don’t always move quickly – I still have CMFs from Series 9-11 lying around that never sold… and those are in new condition. This stuff is all used.
PS – those are the wrong colors of Classic Spacemen to be worth $$ (Black and to a lesser degree Blue are more rare…)
