The Perth Mint of Australia has released four new coins as part of its annual gold koala series. The 2012 Australian Koala Gold Proof Coins are available now in 2 ounce, 1 ounce, 1/10 ounce and 1/25 ounce sizes.
Each of the 2012 Koala Gold Coins is struck from 99.99% pure gold to proof quality. In addition, the one ounce strike is featured in high relief.
Since their debut in 2008, this series of gold coins has featured annually changing reverse designs showcasing the koala. The 2012 design (seen earlier this year with the release of the 2012 Koala Silver Coins) shows a koala asleep on the branch of a eucalyptus tree.
The reverse is the work of Perth Mint artist Aleysha Howarth. Reverse inscriptions include the size of the strike and "9999 GOLD." Also shown on the reverse is the Perth Mint's historic "P" mintmark.
In 2008, the gold coin reverse showed an adult koala in a tree branch with its young clinking to its back. The following year, a koala was depicted sitting on one branch as it reached with its front limbs to another. The 2010 design showed a koala munching on eucalyptus leaves. Last year's 2011 Koala Gold Coins had an adult koala in the fork of a tree with its young climbing up one of the branches.
The 2012 Koala Gold Coins are all struck as legal tender of Australia under the Australian Currency Act of 1965. The face value of the 2 ounce coin is AUD $200, the 1 ounce coin is $100, the 1/10 ounce coin is $15 and the 1/25 ounce coin is $5.
Diameters of the coins are 41.10mm for the 2 ounce, 27.30 for the 1 ounce, 16.60 for the 1/10 ounce and 14.60 for the 1/25 ounce. Thicknesses are 3.90mm, 5.00mm, 1.50mm and 1.40mm from the largest to the smallest.
As seen by those measurements, the one ounce coin is thicker than the others. This is to allow for the high relief image of the strike.
Pricing for coins of the series starts at AUS $145 for the smallest and ranges up to $5,250.00 for the largest strike. Mintages also vary with only 250 of the two ounce, 2,000 of the one ounce, 5,000 of the 1/10 ounce and 15,000 of the 1/25 ounce.
