In 2013 to celebrate the 100th Anniversary of the Birth of Christopher Ironside, the Royal Mint released a Limited Issue Christopher Ironside 50p Fifty Pence Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse design features the Royal Arms by Christopher Ironside while the obverse depicts the Fourth Portrait of Elizabeth II by Ian Rank Broadley.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
