In 2007 to celebrate the Diamond Wedding of Elizabeth II and Prince Philip, the Royal Mint released a very Limited Issue Diamond Wedding £5 Five Pound Proof Coin.
The reverse design is the rose window of Westminster Abbey designed by Emma Noble and the obverse is a conjoint portrait of Queen Elizabeth and Prince Philip by Ian Rank Broadley. These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
