The Perth Mint is joining in the celebrations surrounding the upcoming milestone birthday of Queen Elizabeth II, who will turn 90 years old on April 21. In addition to a stamp and coin cover issued to mark the occasion, the Mint has released three Proof coins with a common commemorative reverse design.
The reverse was designed by Natasha Muhl and features an image of St. Edward’s crown at its center. Inscribed in the field and along the rim are H.M. QUEEN ELIZABETH II, 90th BIRTHDAY, 21-4-2016, the Perth Mint’s “P” mint mark, the weight of the coin, and its metal composition.
The first coin is composed of two ounces of 99.99% gold, measures 36.60 mm in diameter, and is 6 mm thick. This coin, like the silver issue, has been struck in high relief. Only 300 pieces will be produced and it will retail for $4,681.82 AUD ($3,604.17 USD).
A smaller 1/4-ounce gold Proof coin measures 20.60 mm in diameter and 2 mm thick. It has a mintage limit of 1,000 pieces and is available for $635.45 AUD ($489.18 USD).
Finally, the one-ounce 99.99% silver Proof coin measures 32.60 mm in diameter and is 6 mm thick. It has been struck in high relief, its mintage limit is set at 5,000 units, and it is available for $99.09 AUD ($76.28 USD).
The coins share an obverse design that features Ian Rank-Broadley’s portrait of Queen Elizabeth with the inscriptions ELIZABETH II, AUSTRALIA 2016, and the monetary denomination placed along the rim.
Each of these issues comes with a certificate of authenticity. For more information on Australian coins celebrating Queen Elizabeth’s 90th birthday, please visit the Perth Mint’s Web site.
