A distillery worker was given an old bottle of cognac instead of payment. Now, it could be worth $200,000 in an auction.
It has been stored in a family cellar for 140 years, complete with original label.
Sotheby's spirits specialist Jonny Fowle told the PA news agency that the 258-year-old Cognac should still taste good and will have “maintained its character."

The sellers have had the “prized possession" in the cellar of their family home, “untouched for generations."
Their ancestors adopted their son in the 19th century. He then went to work in the Cognac region of France for 10 years, until 1880.
Soon after, the phylloxera insect infestation “wiped out" vineyards across mainland Europe.
“He probably finished his time in Cognac when phylloxera hit," Fowle said.
“He returned home to his family and in lieu of payment he had a huge cart full of bottles of Cognac", which was 'quite normal' for the period."
The family decided to keep three. Including this bottle, which was “already very old at the time.

“They kept it for another 140 years in their family before deciding to sell," he continued.
The bottle is one of only three Gautier Cognac 1762 bottles to survive. The two others, in the Gautier Museum were sold at auction in New York in 2014 for around $58,000, and are smaller.
"The Cognac is still good to drink," Fowle said.
The auctioned bottle was opened in 2014 “but I've not been lucky enough to taste it," he added.
“By all accounts it was enjoyed."
They also praised the condition of the bottle itself.
"The condition of the bottle is really good. There's not been that much evaporation," he continued.
“We can assume the alcohol level in it is pretty high and that would have acted as a preservative for hundreds of years. The liquid in the bottle would have maintained its character."
Fowle was asked if he was tempted to have a sniff of the cognac.
“No! I might be out of a job," he joked.
Family distillery Maison Gautier had obtained a Royal Warrant to produce Cognac from King Louis XV just seven years before the bottle was produced.
Other items up for auction include a whisky expected to be worth $122,000.
The Cognac will be auctioned at Sotheby's online sale, open for bidding from May 14 to May 28, with all items expected to be worth a total £1.1 million.
