Layton Davies, formerly of Pontypridd, was jailed in 2019 for concealing the finding of the treasure and theft after he sold rare Viking and Anglo-Saxon coins and jewellery along with an accomplice.

Following Davies’ conviction, the CPS Proceeds of Crime Division took him to court so that the Confiscation Order could be issued under the Proceeds of Crime Act.

He was ordered to repay the £603,180 he made from selling the stolen treasures, which experts believe provided fresh information on previously unknown alliances between the ancient kings of Mercia and Wessex.

Debbie Price, Deputy Chief Crown Prosecutor of the CPS Proceeds of Crime Division, said: “Greed led Layton Davies to ignore his duty to report the found treasure and instead sell it for his own benefit.

“An experienced detectorist, Davies would have known he was entitled to half of the proceeds of legal sale of the treasure, instead choosing the deprive the landowner and public by stealing this exceptional and significant treasure.

“This case shows that the CPS takes our duty to ensure crime doesn’t pay seriously, Davies has failed to pay so we have taken him back to court and his additional default sentence means he now faces a further five years in prison.”
