In 2004, to celebrate the Golden Age of Steam, the Royal Mint released on behalf of Guernsey a Limited Issue £25 Twenty Five Pound Gold Proof Coin struck in solid 22 Carat Gold to commemorate the Mallard.
The reverse design depicts the Mallard 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.
