The largest gold nugget discovered in California, this famous 156-ounce (4.4kg) chunk of gold was found in 1977 in the Mojave Desert by prospector Ty Paulsen using his trusty metal detector.

In October 2014, the nugget was sold for $400,000 to Margie and Robert E. Petersen, who later donated it to the Natural History Museum of Los Angeles County. In today's money, the nugget fetched a whopping $533,000 (£428k).
