A trove of 2,584 silver coins from the time of the Norman Conquest has been bought in the United Kingdom for more than $5 million — making it the country's highest-value discovery ever made by treasure hunters.
Adam Staples and Lisa Grace found the bulk of the coins, estimated to be from the years 1066-68, in January 2019 alongside five other amateur metal detectorists in the Chew Valley area, 11 miles south of the city of Bristol.
Staples said he and the other detectorists were proud to have found such a significant piece of history. The proceeds, he said, will be split with the landowner.
The coins were purchased by the U.K.’s South West Heritage Trust, an independent organization that supports historical sites, with funding from two charities, the National Lottery and the Art Fund.
The coins will go on display in London's British Museum on Nov. 26, before going on to tour other museums in the U.K., finally settling in the permanent collection at the Museum of Somerset, near where they were discovered.
The discovery, described in a combined press release by the charities as “unprecedented,” was reported to the British Museum’s Portable Antiquities Scheme, which records archaeological finds made by the public.
Under the U.K.’s 1996 Treasure Act, hunters must report an archaeological find to their local coroner within 14 days of a discovery.
Sam Astill, CEO of the South West Heritage Trust, said in a statement: “The hoard symbolizes a pivotal moment in English history and we are delighted to have made this acquisition so that it may be enjoyed by generations to come."
Aleks McClain, a medieval archaeologist, praised the trust's acquisition of the coins.
“It’s vital that such a rare collection as this is kept together, as it will be a fantastic resource for future archaeological research on numismatics and for understanding the Norman Conquest period,” she told NBC in an email.
Unearthing coins that were in use almost 1,000 years ago is exceptionally rare, and Rory Naismith, professor of early medieval English history at the University of Cambridge, said it was a hugely exciting discovery.
Naismith said the collection of coins would have the equivalent of $50,000 in modern buying power, a respectable annual income in medieval England suggesting it belonged to a wealthy group or individual.
The coins were likely to have been buried for safekeeping, a common method in the 11th century. That they were never dug up by their owner suggests to historians that they may have been lost or abandoned because of the Battle of Hastings and the Norman Conquest. This was a period of great turmoil and displacement starting in 1066, when an army, led by William the Conquerer of Normandy, France, invaded and occupied England.
The transition from Saxon to Norman rule was a profound turning point in English history, Amal Khreisheh, curator of archaeology at South West Heritage Trust, said in a video published on its website.
The Norman Conquest was the last successful invasion of England. William the Conqueror defeated King Harold II, overthrew the Anglo-Saxon elite, took possession of the land and redistributed much of it from Anglo-Saxon landowners to his loyal Norman followers, transforming the ruling class, including its language and composition.
“Finds like this bring the past to life on a tangible, human level, and add directly to our knowledge of the eleventh century in a way that very rarely happens with written sources,” Naismith told NBC News on Wednesday.
The discovery draws attention to the grassroots impact of the Norman Conquest, which Naismith said, “meant rapid, sometimes turbulent change at many levels of society.”
Naismith praised the museums and charities of the U.K. for recognizing the historical value of finds like these.
“It is a huge achievement on the part of South West Heritage to have raised these funds, and the hoard will doubtless generate great interest.”
McClain said she hopes this extraordinary discovery will spark public interest in the tumult of 1066 and its aftermath.
"We are only just scratching the surface of what archaeology can tell us about the everyday lives of people who lived through this intense period of change."
