In 2006, to celebrate Great Britons and the Life of Isambard Kingdom Brunel, the Royal Mint released on behalf of Guernsey a Limited Issue Isambard Brunel £5 Five Pound Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse depicts Isambard Kingdom Brunel, 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.
