I'd like to to counter the previous opinion and say these do have value. As SW figures they are very unique but they also cross into Disney collector territory so have a large market.
Either way you will struggle to find many of them for less than £10 each and if you want any of the exclusives you will pay a lot more, the Hologram Stitch as Yoda, Jedi mickey with chip and dale ewoks and the dark trooper Donald.
There are six full serise now and a host of two packs and even a Jedi starship and a jabba skiff playset.
As an average I thing £50 a serise is about the going rate (5 figuers per serise)
The two packs are a bit more varied but around £20 each is about right with the R2-MK droid being a bit more, maybe £30ish
The 3 exclusives will be more, I have seen the Stickh emperor go for £50, but that might be a touch inflated these days, maybe down in the £30'
Not really sure on the Jedi ship and play set. I paid about £25 for each of them last year?
Granted we are not close to vintage prices here but don't knock these, they are great pieces, very unique, not mass produced (although not exactly limited either, but outside of ebay you could only get these from a Disney land for the most part)
I personally love these and they are one of the few full sets of 'modern' figures I have kept and they are great, have a good laugh at the goofy as TC-14 figure and the interesting shape of the drinks tray he is carrying
Anyway, I believe these have a value and will hold it, not vintage prices but among the best modern can offer, and they are a lot of fun, but that is only my opinion.
