There are thought to be about 50 in circulation, with even fewer made from nickel brass like the one sold by RWB Auctions in Royal Wootton Bassett on Wednesday.Experts had estimated the coin to sell for between £500 and £700, but a bidder offered £1,700 for the item.

The coin is thought to have been made by Royal Mint craftsmen before the 20p denomination was released into circulation in 1982.At the time, authorities had not decided whether the coin would be worth 20p or 25p.Known as ‘trial pieces’ or a ‘pattern coins’, such rarities are typically sought by serious collectors.

YouTuber Christopher Collects, who works for RWB Auctions, called the piece “fascinating”.He said: “20p coins are a fixture in our change now, but the Royal Mint seems to have experimented with various ideas before they settled on the seven-sided coin we all recognise.

“Trial pieces would have been used to demonstrate the concept of a new coin to officials and may have been sent out to businesses that handle lots of cash to try out."

The 25p coin is part of a specialist sale of historic and modern currency organised by RWB Auctions.A spokesperson added: “Ofcom has set out the proposed steps companies will have to take to protect children on their platforms under the

, including using highly effective age checks and altering their algorithms to filter out harmful content.”Young carers from Wiltshire are taking part in a national award which aims to raise awareness of the hidden work of the group.

There are 75 young carers at the Royal Wootton Bassett Academy. Kerry Heaphy, deputy head of inclusion said the award scheme helps them "identify our young carers, look out for them and support them".The scheme provides primary and secondary schools across England with step-by-step guidance for schools to gain the practical tools they need.
