The coin was designed by Christopher Le Brun RA and features the Chinese Pagoda, a distinctive and famous monument at Kew Gardens, with a decorative leafy climber wrapped in and around the tower. In 2019, a newer, commemorative edition of the coin was released, as part of the 50 Years of 50p British Culture Set.īut the Royal Mint said: “Nothing gets people excited quite like the original 2009 design.” The Royal Mint said the Kew Gardens 50p is arguably the most sought-after. Only 210,000 coins were released by The Royal Mint, making this 50p coin one of the rarest and most valuable of all the different 50ps in circulation, with one selling on Ebay for £172 this week. The rare coin was released in 2009 to mark the 250th anniversary of London’s Kew Garden. Coin collectors have been urged to check their pockets for a 50p coin that could be worth £172.
