Another interesting coin struck from 5 ounces of pure silver by Perth Mint. It is a tribute of sorts to a popular Chinese legend that tells of celestial guardians.  According to ancient Chinese mythology, the universe was divided into four quadrants marking the winter and summer solstices, as well as the autumn and spring equinoxes. These celestial quadrants were known as the "Four Heavenly Palaces," and each palace was represented by a guardian animal of the appropriate color and element. The reverse of the coin depicts the guardians of the Four Heavenly Palaces, in a colorful finish.  - The Black Turtle symbolizes winter and water.
