The Saddle Ridge Hoard (found 2014)

A couple walking their dog on their own Gold Country property noticed a rusted can poking from the trail. Eight cans later they had 1,427 U.S. gold coins, 1847 to 1894, worth around ten million dollars, the richest buried-coin recovery in American history. Who buried them was never established, and the couple and the exact site remain anonymous to this day. Proof the ground still holds surprises.
