1980’s return of the Jedi/ empire strikes back era figures valuation request

[trf]

Hi all, hoping you don't mind helping me out. My dad is looking to sell his vintage Star Wars toys and was thinking £100 for the lot but I feel like he can get more for it, could someone help me get an idea for a selling price?

Thanks in advance!!!

About £140 or so there mate, so a bit more

If both Chin guns are original and are on the AT AT and the battery cover is there and still works with battery think you would have min £70 to £80 for that ATST looks in good nick, and complete £25 to £30 then the figures
as said min £140 mark there is a Fett figure there but the paint is rough on him
if your dad has any weapons around still for the figures that would bump up the price further
