A 2,221-year-old silver coin dug up as part of a hoard is the oldest piece of Roman money ever found in England.
Dating from 211 BC and found near the Leicestershire village of Hallaton, the coin was uncovered with 5,000 other coins, a helmet and a decorated bowl.
Unearthed in 2000 by a metal detectorist, staff at the nearby Harborough Museum have only just realised its significance.

One side of the coin depicts the goddess Roma wearing her characteristic helmet while mythical twins Castor and Pollux sit astride galloping horses on the reverse.
David Sprason, Leicestershire County Council cabinet member for communities and well-being said: 'Leicestershire boasts the largest number of Iron Age coins ever professionally excavated in England.

'To also have the oldest Roman coin ever found is something very special.'
The type of coin, known as a denarius, was first struck in Rome in 211 BC, making the Hallaton coin a very early version, the council said.

A soldier or unskilled worker living in the first century AD could expect to earn one denarius for a day's work.
The previous oldest known Roman coin found in England was discovered by a metal detectorist in Berkshire last year.

The Hallaton coin is on display at Harborough Museum, Market Harborough, alongside other coins that were excavated at a late Iron Age shrine of the Corieltavi tribe dating to the first century AD.
Archaeologists believe the coins were buried as gifts to the gods, with other finds including a richly decorated Roman cavalry helmet, a unique silver bowl and the remains of more than 300 pigs.

It is thought that the coin may have arrived in England in the purse of an invading Roman soldier after AD 43.

But some archaeologists have speculated that Roman Republican coins such as this were finding their way into Britain before the Roman conquest and are evidence of exchange through trade or diplomacy.

The finds from Hallaton were declared as treasure and acquired by the council with the help of a Heritage Lottery Fund grant.
Professor David Mattingly of the University of Leicester's School of Archaeology and Ancient History described the news as 'exciting'.

He said: 'This hoard has changed our view of just how significant the East Midlands were in this period and this coin is a good example.'
'It indicates there was contact between this region and the Roman Empire despite the distance between the East Midlands and the parts of England the Romans arrived in, like Colchester and Chichester.'

The coin would have passed through many hands, he added.
'It was minted in Rome at the time of the Hannibalic wars and here it is turning up after what must have been quite a long journey,' he said.
