Brick Economy allows you to look up the value of any lego set, see it's historical pricing information and also gives you projections into the growth in it's value.
I wanted to teach my kids about investing and thought about buying a few collectable lego sets and hold them for a few years than sell them. While researching which sets to buy, I came across Brick Economy which made the Lego "picking" much simpler. We now have 5 sets we are invested in and plan on showing my kids the value chart in Brick Economy quarterly to hopefully show them growth in our investment.
