A Northern California couple out walking their dog in February 2013 on their Gold Country property stumbled across a modern-day bonanza: $10 million in rare, mint-condition gold coins buried in the shadow of an old tree.
Nearly all of the 1,427 coins, dating from 1847 to 1894, are in uncirculated, mint condition, said David Hall, co-founder of Professional Coin Grading Service of Santa Ana, which recently authenticated them.
