In 2019 to celebrate the 50th Anniversary of the first UK 50p Fifty Pence coin and the 260th Anniversary of Kew Gardens, the Royal Mint released a very special Limited Issue Dual Dated Kew Gardens 50p Fifty Pence Proof Coin.
The reverse, designed by Christopher Le Burns features the Chinese Pagoda at Kew Gardens while the obverse depicts the Fifth Portrait of Elizabeth II by Jody Clark.
