Best way to sell a large Lego collection in the UK

[Mumbythesea1]

What’s the best way of selling Lego?
DS has decided he doesn’t want to play with it anymore 😢
He has collected a lot over the years.
should I try and separate out the kits? Or sell by KG to a selling site?
whats best?

My adult son sells his on Ebay as individual kits.

Complete kits with instructions and boxes will get the most, especially if they are no longer available to buy new. There are various selling groups on social media if you have the time to do each kit separately. Bulk loose lego goes for much less than kits.

Thank you. I’m going to separate into sets and then start by selling those and see what I have left. Thank you!
