Hundreds of rare 50p coins worth up to £2,500 are still in circulation. The Britannia Coin Company sold the ‘lines over face’ 50p coin made to celebrate the 2012 London Olympics to an anonymous collector for the hefty price this month.
People have now been urged to given their coins 'a quick once-over' before using them. The aquatics-themed 50p was one of 29 different commemorative coins issued by The Royal Mint in 2011, with each coin paying tribute to a different Olympic sport.
However, only 600 of the ‘lines over face’ 50p coins are believed to have been issued before the design was suddenly changed. It is regarded as the rarest cupro-nickel 50p in existence and easily the most valuable according to the Manchester Evening News.
