A unique penny dating from the reign of King Stephen over 850 years ago has been found by a Sheffield metal detecting enthusiast.
The silver penny - which is expected to fetch up to £10,000 at auction, and rewrite the history of early English coinage - was found in a field.
The coin, which dates from a chaotic period of civil war, will be sold at auction in London on April 2.
“This is an extraordinary discovery,” said Christopher Webb, head of the coins department at specialist auctioneers Dix Noonan Webb. “It is tremendously exciting.”
