On that day, the queen (who ascended the throne in 1952) became the first reigning British monarch to reach that milestone. 

The coins are a 1-ounce .999 fine silver dollar, a quarter-ounce .9999 fine gold $25 piece and a High Relief 2-ounce .9999 fine gold $100 coin.

The reverse of each coin depicts St. Edward’s Crown surrounded by branches of the golden wattle, Australia’s national flower. Wattle was depicted in the brooch presented to the queen during her coronation tour of Australia in 1954. 

The inscriptions H.M. QUEEN ELIZABETH II and 90TH BIRTHDAY, the date 21-4-2016, and the Perth Mint’s P Mint mark, also feature in the design, from artist Natasha Muhl.

The coins were approved by Buckingham Palace, according to the Perth Mint. 

Each commemorative coin is individually presented in a gift box within a themed shipper and is accompanied by a numbered certificate of authenticity.
