I bought this lego collection for $150. The mountain cave caught my eye because it was a childhood dream set. I have enjoyed the minecraft sets for a bit but im more into lego star wars. I know the slime is worth some money. My main question is how do I go about selling this big of a collection? I was originally thinking a big auction on ebay, but im not sure. How would you guys go about selling this big collection?
