In 2018 to celebrate the Royal Birth of Prince Louis, the Royal Mint released a very Limited Portcullis 1p One Pence Silver Coin struck in solid .925 Sterling Silver.
The reverse of the 1p One Pence Silver Coin features the familiar portcullis design with chains royally crowned, designed by Christopher Ironside.
The obverse design features the Fifth Portrait of Her Majesty Queen Elizabeth II by Jody Clark.
