A Chinese bowl that a New York family picked up for $3 at a garage sale in 2007 and kept on a mantel turned out to be a 1,000-year-old treasure and has sold at auction for $2.2 million. The ceramic bowl, 5 inches in diameter, is from the Northern Song Dynasty, which ruled China from 960 to 1127 and is known for its cultural and artistic advances. The auction house said the only other known bowl of similar size and design has been in the collection of the British Museum for more than 60 years.
