Wendy The biggest money in the legos are the minifigs, we get so many, we first sort out all the minifigs, and then the blocks we put into 20 lb. Boxes. The minifigs gets about a buck a piece on average, but we had one mini fig alone get us over $50.00. I don't do the legos so I have not learned which ones are valuable yet. The 20 lb. boxes of bricks and Blocks usually get about $200.00. However one of our customers that always buys 1 or 2 of these block boxes, takes them home and sorts by color and shape and makes $2000.00 a box, If you know the rare Minifigs and rare Block colors you can make alot. Just go look on ebay and you will see so many people selling legos. All in all this does not sound like a lot of money, but we can gather a pallet full of legos in a month here.
