1/10 oz Lunar gold Dragon produced by the Perth Mint. 

This coin is from Series 1 of the Lunar Series and was wildly popular with collectors. 

The obverse features the head of state of the British Commonwealth, Elizabeth II, along with the weight of the coin, its purity and face value. The face value of the 1/10 ounce coin is A$15.

The reverse features a traditional Chinese dragon along with the sign for a dragon and the legend: "Year of the Dragon."

This coin very rarely surfaces on the market for sale as collectors prefer to keep them.
