The Perth Mint of Australia will release the 2013 Australian Koala Silver Bullion Coins for sale to the public beginning on November 5, 2012. Four different sized coins will be issued as part of the release, each struck from 99.9% pure silver.
This release continues a series which dates back to 2007. Annually since that point, the Perth Mint has issued the Koala Silver Bullion Coins with each new release featuring a different reverse design.
That annually changing reverse image is a big draw for both collectors and investors. Along with other important factors, it has led the Koala Silver Bullion Coins to be among the most sought after bullion products in the world.
Shown on the reverse of the 2013 coins is the image of an adult koala. The marsupial is shown resting in the fork of a tree. Reverse inscriptions surrounding the design include AUSTRALIAN KOALA, 2013, 999 SILVER and the size of the strike.
A koala was also shown resting in a tree on last year's 2011 Koala Silver Bullion Coins. However, in that design, the adult is joined by one of its young. The previous year, the 2010 Koala Silver Bullion Coin depicted a single koala eating gum leaves.
The newest release will be issued in four different sizes - 1 kilo, 10 ounce, 1 ounce and 1/2 ounce. These coins are struck as legal tender of Australia with face values of AUD $30, $10, $1 and $0.50.
As legal tender, the obverse of the coins depicts Ian Rank-Broadley's effigy of Queen Elizebth II. That portrait is surrounded by the inscriptions of ELIZABETH II, AUSTRALIA and the face value.
Aside from that legal tender status, these coins are struck as official bullion products of the Perth Mint. Accordingly, each also carries the Australian government's guarantee of weight and purity.
The Perth Mint indicates the coins will be struck to meet demand for twelve months. The final mintage of each piece will be announced by the Perth once the production has ended in 2013.
Diameters of the strikes range from 100.60 mm for the kilo coin, to 75.60 mm for the ten ounce, 40.60 mm for the one ounce and 36.60 mm for the 1/2 ounce. Maximum thicknesses are 14.60 mm, 8.70 mm, 4.00 mm and 2.30 mm, respectively. Minimum gross weight is listed at 1,001.002 grams, 311.347 grams, 31.135 grams and 15.591 grams.
