A US couple out walking their dog in their garden stumbled across a modern-day bonanza: 10 million dollars (£6m) 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.
Veteran numismatist Don Kagan is representing the couple, who are not being named. He said today they plan to sell most of the coins.
Before they do, however, they are loaning some to the American Numismatic Association for its National Money Show, which opens on Thursday in Atlanta.
Kagan says some of the rarest coins could fetch as much as one million dollars (£600,000) apiece.
He says the couple, from northern California, want to remain anonymous to avoid having to change their lifestyle.
