Released toward the end of the original Lunar Series I, the 2006 Australia 1 oz Gold Lunar Dog BU is produced by the Perth Mint in .9999 fine gold. This coin contains 1 troy ounce of gold and is recognized as legal tender in Australia. The obverse features Queen Elizabeth II, while the reverse depicts a dog representing the Year of the Dog. In Chinese culture, the dog is often associated with loyalty and protection. The coin continues to be widely collected for both its symbolism and bullion value.
