LONDON (AFP) – A rather costly error by the Royal Mint has seen the issue of tens of thousands of 'dateless' 20p coins -- driving their value up to around 50 pounds each.
There are believed to be between 50,000 and 200,000 of the coins now in circulation, all of them missing the 2009 stamp which was supposed to appear on the back -- or 'heads' side -- of the coin.
It was the first time an undated coin entered circulation in more than 300 years -- the last such error occurred in 1672 under the reign of Charles II.
Describing the mistake as "incredibly rare", the Royal Mint said the error occurred last year during a redesign of every denomination of coin.
The old 20p coin had the date on the front of the coin, but the updated version was supposed to shift the date to the other side. But the coins were minted using an old version of the Queen's head -- one which which does not carry the year.
The London Mint office, a private company specialising in collector coins which has no link to the Royal Mint, is now offering anyone who has one of the dateless coins the chance to cash in.
Nick Hart, a spokesperson for The London Mint Office, said the error could bring the fun of coin collecting to a much wider audience.
"Mistakes like this not only fascinate people but also have considerable value increase significance," he said.
"We believe this extremely rare error will certainly get the public looking at the coins in their pockets again and noticing the excellent new designs launched by the Royal Mint last year on our coinage."
Anyone wanting to trade in their coins should register the find with The London Mint Office.
