Three men have been sentenced to jail for their part in an operation to flood the country with fake £1 coins, express.co.uk reports.
Fifty-four-year-old Kevin Fisher was named the man behind the plot, in which the gang intended to turn gold-coloured discs into fake coins.
The audacious scheme is thought to be the biggest ever involving the production of pound coins.
Fisher, of Goffs Oak, Hertfordshire was arrested last May along with Daniel Sullivan of Hornchurch, Essex and Mark Abbott of Enfield, north London, having been under surveillance by Scotland Yard's elite special projects team.
The gang had stored 1.6 million gold discs plus £100,000 worth of 'finished' coins in two 40ft shipping containers, kept at Parkview Farm in Waltham Abbey, Essex.
The story once again highlights the importance of checking change or implementing robust cash procedures to help prevent the spread of counterfeit money. Almost every month a new report hits the news about the production of fake money, so consumers and businesses must be vigilant, informing the police if they have any suspicions.
Jurors at Southwark Crown Court found Fisher and Sullivan guilty of possessing counterfeit currency and the items necessary for making counterfeit coins. They received 12 years between them. Abbott was given a two-year prison sentence.
Commenting on the scheme, Detective Inspector Bruce South told bbc.co.uk: "These three men are organised criminals who were intent on undermining the UK monetary system. There is nothing fake about the reality they must now face, of life behind bars."
