More than 700 gold coins dating back to the US Civil War have been found buried in a cornfield in the US state of Kentucky. Now, the find is being put up for sale. It is expected to bring millions of dollars.
The "Great Kentucky Hoard" was discovered on a farm earlier this year, according to the company which is selling the coins.
The exact location of the find, and the name of the man who found the coins, are being kept a secret.
In a video posted on GovMint.com, which is selling the hoard, the man is seen digging up the coins in the earth. He is heard saying "this is the most insane thing ever."
The coins were dated between 1840 and 1863 and include US$1 Gold Indians, US$10 Gold Libertys and US$20 Gold Libertys.
Among them are 18 extremely rare US$20 Gold Libertys minted in 1863 in Philadelphia. They could fetch high prices from collectors.
"This is a very important discovery," says Jeff Garrett, a rare coin dealer.
"The stunning number of over 700 gold dollars is like a time capsule of Civil War coins."
Kentucky tried not to fight during the 1861-1865 American Civil War between the South and the North, but it was drawn into the battles anyway.
The coins may have been buried at that time.
"The Great Kentucky Hoard may have been a result of that war, with the coins lost for over 150 years," says Numismatic Guaranty Company, which checked the coins to make sure that they were real.
