A METAL detectorist was stunned after discovering a Roman coin he unearthed 30 years ago was the only one like it — and worth £10,000.
Tom Thomas, 62, dug the silver coin up in a Berkshire field. He said: ‘I was getting a very low signal from my metal detector. I wasn’t going to dig but changed my mind. I had to dig really deep compared to other coins.’
The retired police officer, from Reading, forgot about it until fellow detectorist Mark Becher suggested it was rarer than first thought. The pair began contacting experts and learnt it was a 2,000-year-old Carausius Denarius Roman coin.
Mr Becher said: ‘I was staggered when I saw the coin.
‘I’d never seen anything like it. As far as we know, it’s the only one of its kind in the world.’
The item — which dates to 286-93 AD — will be sold at Hansons Auctioneers with a guide price of £10,000 on August 27 in Etwall, Derbyshire.
