In 2000, to celebrate the Centenary of Queen Elizabeth, the Queen Mother's 100th Birthday, the Royal Mint released a very Limited Issue £5 Five Pound Silver Proof Coin struck in solid .925 Sterling Silver Certified Slabbed and Graded by PCGS as PR70 DCAM.

For his superb portrait of the Queen Mother, Ian Rank Broadley worked from photographs which the Queen Mother graciously allowed to be taken for this very special purpose.

To symbolise The Queen Mothers century, he has included cheering crowds in the background, those in Victorian dress rejoicing at her birth and those in modern dress celebrating her hundredth year. Below the portrait appears a representation of her signature.
The obverse is the portrait of Queen Elizabeth II by Ian Rank Broadley FRBS, FSNAD.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
