6-pound gold 'Butte Nugget' up for sale in California

SAN FRANCISCO – One of the biggest gold nuggets found in modern times in Northern California's historic Gold Country is going up for sale.

Weighing in at more than 6 pounds, the so-called "Butte Nugget" is expected to carry a price tag of $350,000.

The San Francisco Chronicle reports the owner of the nugget asked dealer Don Kagin to keep his name and the location of the discovery secret.

What is known is that it was found in July by a gold hunter on public land in the Butte County mountains.

The nugget will be unveiled Thursday at the San Francisco Fall Antiques Show at Fort Mason.
