10 wildly expensive Lego sets for the builder who has everything

Lego bricks do not come cheap. 

Just ask Zhao, the Chinese artist whose Lego sculpture worth $15,000 fell victim to the clumsiness of a small child at a Lego Expo on Sunday. The sculpture, a brick version of Nick from the animated film Zootopia, fell to pieces within an hour of the exhibit's opening. That's three days of work undone in an instant.

On the bright side, $15,000 worth of Lego bricks are worth the same amount whether they're assembled or dissembled. And isn't the building part 99.99 percent of the fun? 

Plus, while $15k for what are essentially toys may seem high, that price isn't particularly surprising considering the truly baffling prices of retired Lego sets, many of which fetch much more than they did back when they were still on store shelves. Need evidence? Just take a peek at Brick Picker, which serves as a guide to some of the company's priciest sets. But hey, we're not judging. If you're going to collect something, it might as well be something that'll make you money in the long term.

But still ... this is some seriously expensive plastic.
