An archaeologist from Oxford Cotswold Archeology (OCA) has made an exciting discovery of 321 11th-century AD silver coins (319 full pennies and 2 cut halfpence) in mint condition near the site of a future nuclear power station on the Suffolk coast. This finding sheds light on the social and political unrest of the 11th century and suggests that the change of government following the coronation of Edward the Confessor in 1042 caused significant turmoil among the population. This collection may have belonged to a local influential figure who felt threatened by the political changes and chose to bury his wealth as a precaution.

The newly discovered cache of coins was carefully wrapped in cloth and lead.

The coins in the hoard were issued during the reigns of Harold I “Rabbit’s Foot” (1036-1040), Harthacnut (1040-2), and Edward the Confessor (1042-1066).

Most of the coins date back to the reign of Harold I, with Harthacnut issuing significantly fewer, and only 24 issued by Edward the Confessor.

While the majority of coins were minted in London, some were also minted in Thetford, Norwich, Ipswich, Lincoln, and Stamford.

A few coins were issued by smaller mints such as Langport and Uxbridge in southwest England, making them extremely rare.

“This hoard of coins offers a valuable glimpse into the historical context of that era, indicating that Edward the Confessor’s ascension to the throne was a time of uncertainty and societal unrest. This further supports the idea that it was a period marked by apprehensions,” said Alexander, a coin expert from OCA.

“The analysis of this coin hoard was a collaborative effort involving experts in numismatics, finds, conservation, and project partners.”

“It is a privilege to contribute to bringing this story to life.”

Despite representing considerable wealth for the time, these coins likely belonged to individuals of moderate status rather than high-ranking individuals.

They were probably a savings pot of a local influencer and were roughly equivalent in value to a small herd of cattle at that time.

“The hoard was affectionately named Masu for obvious reasons, so discovering it was truly an honor,” said OCA archaeologist Andrew Pegg.

“When I unearthed it, I saw the edge of a coin peeking out, and I was amazed!”

“It’s an impeccable archaeological time capsule,” he added.

“The insights we’re gaining from it are remarkable, and I am proud to contribute to the history of my corner of Suffolk.”

The mid-11th century in England was a period of uncertainty and shifting loyalties.

Edward the Confessor’s coronation in 1042 followed over 25 years of rule by Danish kings Canute, Harold, and Harthacnut. This event reinstated the House of Wessex on the English throne.

The change in leadership likely sparked uncertainty and apprehension among the populace.

Specifically, some affluent individuals connected to the previous regime were either exiled or had their assets seized after Edward’s coronation.

The hoard’s owner may have buried his wealth in fear of political changes, hoping to retrieve it later as a safety net.

“We may never fully understand why this treasure was left undiscovered,” concluded the archaeologists.

“The discovery of an 11th-century coin hoard is truly extraordinary,” said Damien Leydon, Site Delivery Director at Sizewell C.
