The couple who uncovered a trove of buried treasure on their property, and only identified as "John" and "Mary," say most of the coins will be sold on Amazon, they will use the discovered fortune to keep their home in California as well as donate to charities.

It was on Tuesday that Kagin’s announced that the couple had discovered a buried treasure while out walking their dog on their property last February. They noticed a rusty old can protruding out of the ground and upon closer inspection, the can was found to be filled with gold coins. They continued looking around the immediate area and would eventually unearth eight cans filled with gold coins dating from the mid to late 1800s.

Their discovery is the largest buried treasure to be unearthed in the United States. This newest California discovery dwarfs the previous record holder, $4,500 unearthed in Tennessee by construction workers in 1985. It was sold for approximately $1 million. This newest trove of treasure has a face value of about $28,000 and could sell for as much as $10 million. It has been named the Saddle Ridge Hoard.

The couple had hiked the area with their dog on multiple occasions. They had noticed previously that an old, rusty, tin can had been hung in a tree and had been there for such a long time, that the tree had grown around it. They discovered the treasure at the base of the tree, not knowing what it contained until they were on their way home with the unnusually heavy can. Once it was discovered what they had, they went back to eventually uncover eight cans containing 1,400 gold coins.

They secreted their find for a time before reaching out to to the numismatics firm of Kagin’s. Kagin’s carried out the assessment of the double-eagle coins and found that the majority of the golden hoard are in mint, uncirculated condition.

Some of the coins will go on sale on Amazon. It will be the first sales of coins that Amazon will conduct. The proceeds of the sale will be used to pay down personal debt of the couple, which includes debt owed on their home. They also plan to donate to several local charities.

Some of the coins will go on display at the American Numismatic Association’s “National Money Show” that begins on Thursday in Atlanta.
