Silver coin with an additional insert made of an ornamental mineral.

This year's edition of the Great Southernland series was enhanced with an ornamental insert made of "snake skin" jasper (Snakeskin Jasper), an ornamental variety of jasper, a chalcedony in the quartz group. It gets its name from its characteristic snake-skin-like patterns - wavy lines, spots and bands in shades of red, pink, cream and brown. The mineral has a hardness of 6.5-7 on the Mohs scale and is well suited for grinding and polishing. It is found in Australia, South America and Africa, among other places. It is most commonly used in jewelry and as a gemstone in the form of cabochons and beads. In esoteric traditions, it is attributed with protective effects and promoting inner peace.

The reverse of this unique coin depicts the Australian continent made of red jasper, whose natural colors and patterns contrast perfectly with the black background, emphasizing the unique character of the design. The composition is surrounded by an intricate ornament showing various species of fauna characteristic of Australia, which further emphasizes the symbolism and importance of nature in the country's culture. The obverse of the silver coin is decorated with the image of King Charles III, traditional for Perth Mint products, depicted on an ornate openwork background, which adds elegance and sophistication to the whole. The entire issue was minted in the highest quality mint proof, so that every detail of both the reverse and obverse is extremely precisely reproduced. The coin was presented in an elegant display box, making it an ideal collector's item as well as a unique gift. The limited nature of the issue further enhances its value and appeal among numismatists worldwide.
