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