Ever think you could earn $10 million walking your dog? A California couple did just that last spring when they stumbled across 1,427 gold coins in their yard.

The couple found metal cans packed with gold coins while walking their dog on a path on their property, Reuters reports.

“I saw an old can sticking out of the ground on a trail that we had walked almost every day for many, many years," a member of the couple, identified only as John, said in an interview with the numismatic firm representing the pair.

"I was looking down in the right spot and saw the side of the can. I bent over to scrape some moss off and noticed that it had both ends on it," said the other member of the couple, identified as Mary.

The coins date from 1847 to 1894 and were minted in San Francisco, CNN reports. Though the actual face value of the hoard is valued at about $27,000, experts say that some of the coins could go for $1 million each.

Some of the gold coins in the treasure rated as some of the finest known examples of their kind, said David Hall, co-founder of Professional Coin Grading Service, which certified the couple's find, according to USA Today.

The discovery has been named the Saddle Ridge Hoard for the area of land in which the riches were buried and is thought to be one of the greatest discoveries of treasure in U.S. history, according to the coin collecting news site Coin Update.

"The Saddle Ridge Hoard discovery is one of the most amazing numismatic stories I've ever heard," said Don Willis, president of Professional Coin Grading Service, according to Reuters. "This will be regarded as one of the best stories in the history of our hobby."

It is unclear how the coins got where they were or who buried them.

Most of the coins will sell on Amazon, while others are scheduled to go on display at the American Numismatic Association show in Atlanta later this month, Reuters reported.

The couple plans to use their newfound wealth to help "people in our community who are hungry and don't have enough to eat. We’ll also donate to the arts and other overlooked causes,” Mary said. “In a way it has been good to have time between finding the coins and being able to sell them in order to prepare and adjust.”
