Check your wallet, because if there's a certain 50p in there then you could be quids-in.
The Royal Mint has revealed that the Jemima Puddle-Duck 50p from last year's Beatrix Potter set of coins is the apple of many coin collector's eyes, as it is incredibly rare.
It was released alongside coins featuring Peter Rabbit, Squirrel Nutkin and Mrs Tiggywinkle as part of a 150th anniversary set of change.
And mintage stats now show the Jemima Puddle-Duck coin is the rarest in the collection. Only 2.1 million were released into circulation, compared to Peter Rabbits 9.6 million.
Experts at Change Checker reckon that Jemima Puddle-Duck is the 8th rarest coin overall in circulation.
A spokesperson for the company told the Metro: "When one coin in a series has a much lower mintage figure, collectors struggle to complete the set.
"We've started to see evidence of this as swap requests from our swap centre users have increased dramatically.
"For every one Jemima Puddle-Duck coin we see listed as available to swap, there are more than eight users requesting this coin."
Royal Mint coin designer Emma Noble was chosen to create the illustrations.
Back when it was released the brand manager for Peter Rabbit at Penguin Ventures Thomas Merrington told the Mirror: "We are so delighted to be working once again with The Royal Mint on a new series of Beatrix Potter coins.
"The success of the original range is testament to the incredible craftsmanship and attention to detail that Emma Noble achieved in her designs and also to the love and affection shown towards Beatrix Potter's characters by the general public," Merrington added.
Here's what people have been saying about the coin on Twitter:
Amazing a 50p can go for so much money.
