In 2004, to celebrate the Golden Age of Steam, the Royal Mint released on behalf of Alderney a Limited Issue Merchant Navy 21C1£5 Five Pound Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse design depicts the Merchant Navy 21 CI while the obverse has the stunning portrait of Her Majesty Queen Elizabeth II designed by Ian Rank Broadley.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
