• The set of five Canadian coins, introduced in 1990, featuring the portrait of Queen Elizabeth II wearing a diamond crown as well as a diamond necklace and earrings.

• Coins are displayed in a custom coin wallet with a Certificate of Authenticity.

• In 1990, a new portrait of Queen Elizabeth II was introduced on Canadian coins.

• The new portrait shows a mature image of the Queen, who is wearing a crown for the first time. 

• This was the third portrait of Queen Elizabeth II on circulating Canadian coins, after the original portrait in 1953 with a laurel wreath and the second portrait in 1965 with a tiara.

• The diamond design was created by Dora de Pedery-Hunt, the first Canadian artist to design a portrait of the Queen for Canadian coins.

• The diamond crown is circular and is decorated with roses, shamrocks, and thistles to represent England, Ireland, and Scotland, respectively.

• The crown was made for King George IV (reigned 1820-1830) and was worn by Queen Victoria for her formal portraits. 

• Queen Elizabeth II wears the crown for the opening of Parliament.

• This design was used on Canadian coins until 2003; it was replaced with an uncrowned portrait.

• Each coin is a classic that is now out of issue.
