Valuation of vintage 12" figures

[fuzzybuzzytoys]

Hi

I have listed on eBay a number of vintage (1978) 12" figures. I am completely guessing at prices (with some help from completed listings) and was wondering if anyone here could help me value them more accurately. All figures, apart from the Princess Leia, are in very condition and complete with all accessories. The Leia is boxed but is missing her brush and comb. The figures are..

Luke Skywalker
Darth Vader
Jawa
Han Solo
Princess Leia
C3PO
R2D2
Stormtrooper
Chewbacca
Ben Kenobi

For (very poor) pictures please look here

Any help valuating these would be great
