Shoppers have been urged to check their change in case they might be unknowingly in possession of a super rare 50p coin.
The special specimen was released back in 2009 to celebrate the 250 years since Kew Gardens was opened in London. One of the currency sold for a whopping £150 online - a remarkable 300 times its face value.
Collectors are willing to spend big to get their hands on one of the items. According to the Royal Mint, approximately 210,000 of them were made.
