A California couple spotted the edge of an old can on a path they had hiked many times before. Poking at the can was the first step in uncovering a buried treasure of rare coins estimated to be worth $10 million.
"Since 1981, people have been coming to us with one or two coins they find worth a few thousand dollars, but this is the first time we get someone with a whole cache of buried coins… It is a million to one chance, even harder than winning the lottery," Kagan told ABCNews.com.
The couple is trying to remain anonymous after finding the five cans of coins last spring on their Tiburon property in northern California and conducted an interview with Kagin.
"I saw an old can sticking out of the ground on a trail that we had walked almost every day for many, many years. 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," they said.
It was the first of five cans to be unearthed, each packed with gold coins.
"Nearly all of the 1,427 coins, dating from 1847 to 1894, are in uncirculated, mint condition," said Kagan told ABCNews.com.
He said Tuesday that the couple plan to sell most of the coins, but before they do, they are "loaning some to the American Numismatic Association for its National Money Show, which opens Thursday in Atlanta."
"Some of the rarest coins could fetch as much as $1 million apiece," said Kagan. He also said that they wish to sell 90 percent of the collection through Amazon.com and on the company's website.
Kagan and his colleague David McCarthy, senior numismatist and researcher at Kagin's, met with the couple last April, two months after the hoard was found.
When McCarthy and Kagan told the couple that their bonanza will be in the annals of numismatic stories for quite some time, the couple said, "It would have been quite a pity not to share the magnitude of our find. We want to keep the story of these coins intact for posterity."
