From The Scotsman: Rare Coin of Mystery Roman Emperor Found in Field.
A man with a metal detector has unearthed a Roman coin so rare it bears the face of a mystery emperor who "ruled" Britain for a matter of days.
Brian Malin, a father-of-one from Oxfordshire, unearthed the bronze coin in a field in Oxfordshire bearing the face of Emperor Domitianus.
It is only the second coin in existence to bear the image of the self-proclaimed ruler of Britain and France in 271AD.
A similar coin was found in France 100 years ago but until now its uniqueness had meant both Emperor Domitianus and the coin were dismissed as a hoax.
Historians say the British discovery confirms the French find is genuine and Domitianus existed.
They believe he was an upstart from the Roman legion who was ousted for treason for daring to declare himself emperor and have the coins made.
Mr Malin found the coin in a field in April last year, 10 miles south-east of Oxford.
The coin was among a pot of 5,000 all bearing the heads of emperors and stuck together, providing the perfect "timeline" for archaeologists. [continue]
