Hi,
Those are some nice Jedi MOCs
I would suggest the following prices.
NN = £175
HH = £225 shame about the bubble crush.
Snag = £250
4Lom = £200
Snow Tropper = £215 what a shame about the crease.
Those are my valuations, but it maybe worth pitching them a bit higher and see what happens.
It would be worth looking at some eBay sold prices too.
Good luck with whatever you decide to do with them.
If your looking to sell I might know someone looking for clear bubble Jedi MOCs (And before anyone chips in its not me
)
