2002 Gold Full Sovereign Elizabeth II Proof

2002 sovereigns have a shield design to celebrate the Queen's Golden Jubilee year. This was only the second time in over a century that a design other than the familiar St. George and Dragon reverse had been used on British gold sovereigns. 
The last date to use a different design than the St George and the Dragon reverse was 1989, to celebrate the 500th anniversary of the very first gold sovereign. 

Obverse

The obverse shows the Ian Rank-Broadley portrait of Queen Elizabeth II. 

Reverse

The reverse design was unique to the 2002 coins. It was designed by Timothy Noad and shows teh shield of the Royal Arms.  The design is reminiscent of the 1838 reverse struck during Queen Victoria’s reign.
