In 2006, the Royal Mint released a very special Limited Issue Silver Proof 13 Coin Collection to celebrate the 80th Birthday of Queen Elizabeth II and contains special Silver Proof versions of the entire range of United Kingdom circulating coins.
They are accompanied by the four Silver Maundy coins, the tiny coins distributed by the Queen to elderly people in a service on Maundy Thursday. These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
