2. Manhattan Parking Spot - $1 million
This parking spot in downtown Manhattan was sold for six times the average cost of an American home. As any New York City driver knows, that's a bargain!

4. Crystal Piano - $3.2 million
This crystal piano was used for the Beijing Olympic Games, and it was purchased at auction by a private bidder for a record $3.22 million U.S. dollars! I bet it sounds like pure gold.

14. Antilia - $1 billion
Named after a mythical island, the only thing mythical about this building is its price. Owned by Indian billionaire Mukesh Ambani, this 34-story home is designed to withstand earthquakes, and it contains three helipads and a parking garage that holds 160 cars. Due to its mammoth size, the building requires 600 full-time staff members to keep it running.

This is no ordinary boat. The History Supreme is a yacht made from solid gold and platinum. It also contains statues made out of real dinosaur bones. It was bought by an anonymous Malaysian businessman.
