A British couple accidentally stumbled upon an 18th-century treasure, worth more than £750,000.

The British newspaper "The Independent" reported that the couple found the treasure in their kitchen, and it was sold at auction for 754,000 pounds (approximately $836,000).

The couple discovered more than 260 ancient gold coins under the floor of their kitchen during an ordinary repair, and the coins were hidden inside a small jar under the 18th-century floorboards.

The newspaper pointed out that the treasure was originally owned by the Fernley Maesters family, which was famous for importing and exporting timber, iron ore and coal, and some of its members worked as members of Parliament in the early 18th century.

Joseph Fernley and Sarah Meister married in 1694 and lived in the village of East Yorkshire.

Joseph died in 1725 at the age of 76, while Sarah died at the age of 80.

The group "Spink & Sun", which sold the treasure in London, described the final sale price as "extremely exceptional", and it was initially estimated at between 200,000 and 250,000 pounds.

The Independent reported that the discovery of the treasure attracted the interest of many around the world, and the collection was sold in the form of individual pieces, for a total of 754,000 pounds.

Gregory Edmund, an auctioneer, said the treasure is an amazing find and dates back to about 120 years of English history.
