To celebrate 150 years of Beatrix Potter, The Royal Mint produced official UK 50p coins and the uncoloured coins featuring the designs will be released into general circulation later this year. In addition to Peter Rabbit, another three collectible coins will be released later in the year to make up a four piece collection. This is the first time a children’s literary character has appeared on a UK coin.
