Gold Country couple discover $10 million in buried coins --- Some dream of roaming the Earth to hunt buried treasure. One Sierra Nevada couple didn't have to go that far. They dug it up in their backyard - about $10 million worth, in 19th century U.S. gold coins stuffed into rusty cans. -- It's believed to the biggest hoard of gold coins ever unearthed in the United States. And it's going on sale soon. -- The bonanza emerged last year as the man and woman were walking their dog on their property in the Gold Country and noticed the top of a decaying canister poking out of the ground. -- They dug it out with a stick, took it to their house and opened it up. Inside was what looked like a batch of discs covered in dirt from holes rotted through the can. - More, Kevin Fagan, sfgate,, at: http://www.sfgate.com/bayarea/article/Gold-Country-couple-discovers-millions-in-buried-5266314.php
