The best way to list Lego

[BeacauseImAnElf]

My dc have a huge amount of Lego that they don't play with so I want to sell it. Some of it is from when me and my cousins were young.
We have listed the Base plates separately but I'm not sure how best to do the loose bricks and pieces.
Any ideas please?

List them by weight in 500g and 1kg bags - the fairest way all round.

Get as many sets together as you can. If you don't have instructions you can Google them. Sets will sell better than loose bricks. Then put the rest in bags by weight and sell those.

Can I hijack and ask about the minifigures? We had a lot of Star War sets which are now not complete or completely mixed up - I'd never manage to recreate them as sets at this stage. But I have kept the little Yodas and other StarWars people separate - should they be sold separately?

It's probably worth a try. You could also sell all the Star Wars stuff as "bundle of Star Wars Lego, incomplete sets". If you know what you had, say that too (eg "parts of Millennium Falcon"). There are websites where people can look up set inventories (listing every part came with the set), find instructions and buy spare parts, so they might well be interested in buying the bundle and then finding the missing parts themselves.

Many thanks Belfast - that's really helpful. Am braced to go upstairs and start sorting. Any minute now. Not stalling at all.

Or you can just send all your Lego to me and I'll play with it! and be divorced by DH for bringing more Lego into the house

Honestly, if you can separate out even a couple of sets, you'll get more money, but even if not, it should be worth a fair bit!

Mini figures will sell separately or in groups, especially now in the run-up to Christmas.
Example - ds really wanted the £200 Lego Ewok village. Had to tell him it wouldn't happen.
He let slip he only really wanted it so much because of two of the figures. Which were about £10 in a group on eBay. Very happy miniCitrus.

I suspect the City stuff won't sell so well but will try with the cool parts shown in pictures. Last year we got a Millennium Falcon minus instructions and only two missing bits which we found in ds's room - but did take about 15 hours to wash and assemble it, so what we saved in cost went in time.

Hassled I'd be interested in buying incomplete Star Wars sets, and I'm sure others would too. My ds doesn't mind too much if sets are incomplete, and he'd love random Star Wars mini figs.

Because if you can be bothered to recreate the sets the pieces came from you'll make more money, but otherwise people like me would buy a job lot. I'd prefer if you kept it all together or if separating the bricks, keep any unusual colours together in case they come from the same set. (E.g. all khaki green / bright blue together, rather than all of a particular size like all small bits together).

I've just sold quite a bit of lego... I built up all the sets together with the instructions and listed them separately.
I got all the 4 x 2 blocks and stuck them together so they were around the size of an A4 piece or paper, that way you can send them in an envelope as a 'large letter' (72p)rather than selling them in a pile and having to post them as a parcel (£2.80). Did a similar thing with other size blocks. Managed to sell a lot, and not too expensive on the postage.
If you are selling lots of lots, then put a raffle ticket type number on them when you photo them, then put the bricks and raffle ticket in a clear bag. When you sell them they are easy to identify, and all ready packaged in a bag. Saves loads of time.
