One morning in February of 2013, much like any other morning, a couple in California were walking their dog along their property. But on this particular walk, one of them noticed something strangeon the side of the trail. The woman, Mary, had spotted an old tin can poking out of the ground.

Intrigued, Mary and her husband John carefully worked the tin out of the dirt. As they did, they uncovered something that would change their life forever: 1,411 gold coins. The coins wereobviously old, minted somewhere between 1847 and 1894, but they were in good condition. Incredibly, as the couple found out shortly afterward, they were worth about $10 million dollars.

It was the largest discovery of lost treasure in U.S. history. Yet no one could figure out how it got there.

But why would someone bury a fortune in coins on their property and never come back to claim them? There are a few possibilities. Some have suggested that the coins came from a 1901 bank heist inSan Francisco when an employee walked out with around $30,000 in gold coins. Given the timing and the value of the coins stolen, it would make sense.

Unfortunately, the U.S. Government has stepped in to rule this theory out. According to the Treasury, the coins found in the horde don't match those you'd expect to see from that particular bankrobbery.
