Some nice cards there. Pity Lando isn't sealed as he's surprisingly hard on that card (Palitoy 45B).
The pick of them is the Power Droid. That's a Palitoy 45A card and pretty much rocking horse poo. Even with that crushed stem you've got to be talking north of (I'd guess) £2,500? Maybe add another grand to that, I really don't know. The world of normal pricing appears to be a thing of the past.
Don't sell any to PMs. That Palitoy 65 back Stormtrooper is easily £300+ nowadays and even smelly Dengar is £150, maybe even £200.
If you're looking to sell and get the best price, stick the PD into an auction house like Vectis. Let it go to auction to get the best price. You'll have a fair few people trying to get it for £2k or less but be patient and send it to a decent auction house. Drop me a PM if you want putting in touch with the chap who'll sort it out for you.
