Once again, in 2018, The Royal Mint put new Beatrix Potter coins into circulation. This time we saw Peter Rabbit munching on some radishes, much to the dismay of Mr McGregor. However, the 2009 Kew Gardens 50p remains by far the rarest coin in circulation, with a mintage of just 210,000: Like the majority of the works on paper collection, they're not on permanent display to avoid the watercolour fading but are available to view by appointment in the Prints and Drawings study room. View a selection in the online gallery below. The design also features a profile portrait of Beatrix Potter and Peter Rabbit can be seen at the bottom of the design. It's a rather small depiction of the cheeky rabbit, but he's there!

Here’s how it compares to other low-mintage designs, including other Beatrix Potter tributes, and which coins you should look out for. The rare 2018 Peter Rabbit design depicts the character chomping on a radish (Photo: PA) How rare is the Peter Rabbit 50p coin? The 2018 edition – the rarest to look out for – shows the rabbit as he was painted by the author, happily biting into radishes in the garden of the curmudgeonly Mr McGregor.Presented to the Museum by Beatrix Potter's executor in 1946, they illustrate the story of Peter Rabbit's sister, Flopsy and her family and how they narrowly escaped being eaten by Mr McGregor. There were 32 drawings for The Tale of The Flopsy Bunnies in Potter's will, which were presented to the British Museum in 1946. The group consists of 28 watercolours reproduced for the front cover and the illustrations beside the text, along with four preliminary studies for them, two of which are executed entirely in pen. They're something of an exception in the Museum's graphic collection as book illustrations have never been the focus for collecting, but such was the fame and quality of Beatrix Potter's drawings that they were gratefully accepted and have featured in two recent external exhibitions of her work. Potter's later life saw her depart from writing to focus on her work relating to land sustainability and conservation. She and William enjoyed thirty years of marriage living a simple life in Near Sawrey, uninterested in the trappings of wealth.

By the age of 14, she had started a journal, written in code, to record her thoughts, ideas and sketches and kept it up until the age of 30. Her early sketches included detailed images of her pets and other animals. Her father, a talented amateur photographer, had friendships within the London art world including the Pre-Raphaelite painter John Everett Millais (1829–1896), whose family would holiday with the Potters in Perthshire, Scotland. Millais recognised Potter's talent, telling her: 'Plenty of people can draw, but you have observation.' With the encouragement of her father, Potter went on to study at the National Art Training School in London (now the Royal College of Art). Following the popularity of this coin, the more common 2017 edition depicted Peter side-on as he hopped towards adventure. In fact, this coin and the 'Flopsy Bunny' 50p of the same yearare the rarest of all the circulation Beatrix Potter 50p coins.

In 1903, following the success of The Tale of Peter Rabbit, came The Tale of Squirrel Nutkin, a story about a red squirrel's narrow escape from an owl called Old Brown.
