The unique silver penny minted for Æthelberht II found by metal detectorist Darrin SimpsonA unique Anglo-Saxon silver penny which provides a clue to the murder of a saintlyEast Anglian king by a neighbouring monarch has been found in a Sussex fieldby a metal detectorist. The 1,200 year-old coin minted during the reign of ÆthelberhtII will be auctioned at Dix Noonan Webb, the international coins and medalsspecialists, in London on 11 June 2014, when it is expected to fetch £15,000 to£20,000.

Darrin Simpson, a 48 year-old pest control specialist from Eastbourne, Sussex, washurrying to shelter from a hailstorm in early March when he picked up a signal on hisdetector. Despite the appalling weather he stopped, dug down 6-8 inches and foundthe penny which has been identified by experts as the only one of its type everdiscovered.

Mr Simpson, who has been a metal detectorist for 12 years, had been working his wayacross the unidentified site in Sussex for about an hour when he was caught in thehailstorm. As he moved quickly, planning to take shelter under some trees, he got asignal similar to others he had picked up that day. As they had all turned out to beSecond World War era .303 bullet cases, he was not optimistic as he stopped to dig.

"I thought it was a Saxon coin, the first one I had found, and I was very happy aboutthat," said Mr Simpson. It was not until he contacted the Early Medieval Corpus ofCoin Finds at the Fitzwilliam Museum in Cambridge that he realised the fullimportance of his discovery. "It was a bit of a shock really, I couldn't sleep for twonights after it was identified," he said. "The condition is really good. This is a uniquecoin. I doubt if I will ever find anything better."

The coin is only the fourth ever found from the reign of Æthelberht II, a shadowyfigure who ruled East Anglia in the late 8th-century. The other three are all inmuseums and have a different design. The coin found by Mr Simpson is the first tohave Æthelberht's name and the title REX on the same side.

"This new discovery is an important and unexpected addition to the numismatichistory of 8th century England," said Christopher Webb, head of the coins departmentat Dix Noonan Webb.

Little is known about Æthelberht II's reign but stories about his piety and hisgruesome end ordered by Offa, king of neighbouring Mercia, have survived down thecenturies. His reign over the kingdom of East Anglia is thought to have begun in 779.Fifteen years later in 794 he reluctantly agreed to marry Eadburh, Offa's daughter,and set off to visit her at the Mercian king's villa at Sutton Walls in Herefordshire.

In a scene worthy of the television series Game of Thrones, Offa's queen Cynethrythpersuaded her husband to have their guest killed and Æthelberht was seized, boundand beheaded. Even in those brutal times, the murder of one king by another was rare.

According to medieval legend, Æthelberht's severed head later fell off a cart and,after being found in a ditch, restored a blind man's sight. The dead king was declareda saint and became the focus of a religious cult in East Anglia. Many parish churchesin Norfolk and Suffolk are still dedicated to himMedieval brass depicting the headless St Ethelbert with Christ stained glass in St Ethelbert'sÆthelberht II Church, Alby, Norfolk

The coin to be auctioned at Dix Noonan Webb may have been one of the reasons forÆthelberht's terrible end. The East Anglian king is believed to have struck the otherthree known coins from his reign with the approval of his much more powerfulneighbour Offa. However the newly-discovered penny looks like an act of defiance bythe increasingly ambitious Æthelberht.

The fact that Æthelberht's name and the title REX (King) appear on the same side ofthe coin may have demonstrated a degree of independence that was simply too muchfor Offa and Cynethryth to bear and they decided to kill him. How this penny came tobe in a Sussex field will never be known but its discovery by Mr Simpson provides uswith a possible motive for a 1,200 year-old Anglo-Saxon royal murder.
