Id be very interested in the carded Slave leia, the MB jigsaw (which has slave leia on the front) and the ESB game cartridge
Pricing up.
Even though many will say there isn't a lot of particular value here theres three ways of looking at it
1. Sell as a bulk deal. The carded figs to a bulk buyer will be no more than £2 each. The micromachines fleet, about £1, the battle packs £3, the action fleet probably a bit more etc etc. The 12" £4. See where I'm going. On first perusal just for the star wars stuff, anything around the £120 - £150 should give incentive for a bulk buyer before shipping / petrol costs. Its worth way more individually than that. Way more and that bulk seller will look to triple/quadruple the output, but they will put the graft in that you don't want to do for a bulk sale. There is some tat there, but the POTF2 creatures and ships do sell well. I had a bunch of those recently and they flew. The micromachines / action fleet stuff does move slower but there are some nice pieces there.
Just glancing through (because you could spend the time putting these into ebay sold listings yourself

)
figs £50 due to the repetition
action fleet £20
books - £5 (total including the vintage)
12" around the £20 total
3 packs £10 total
ships and creatures £50
The rest is largely bunce which would take a bit longer to sell.. but theres a few oddish items that could surprise.
2. Sell individually. You'd probably make a decent amount and at LEAST double what a bulk seller would pay.
3. Sell in lots. Figs. Play sets. Micro machines. Only thing there is the bunce and tat would likely not sell.. (you could always give it away as a charity fundraiser).
this is just my opinion, I am a tight arse though.
