Celebrate the timeless wisdom of Indigenous Australian storytelling with the 50th Anniversary of The Rainbow Serpent 20c Coloured Uncirculated Limited Edition Postal Numismatic Cover (PNC), a exquisite collector's treasure that honors a landmark in children's literature. This limited-edition release, restricted to just 500 pieces worldwide, encapsulates the enduring legacy of Dick Roughsey OBE's iconic 1975 book, The Rainbow Serpent, illustrated by the Lardil artist from Mornington Island. At its heart lies a vibrant, coloured uncirculated 20c coin struck by the Royal Australian Mint, depicting the mythical serpent—known as Goorialla to the Lardil people or Almudj to the Bininj/Mungguy custodians of Kakadu National Park—that slithered across the ancient landscape, carving rivers, gorges, and sacred sites in a creation tale shared by countless First Nations peoples. Affixed to a premium envelope measuring 230mm by 162mm, the coin is accompanied by an exclusive minisheet featuring two Kakadu National Park stamps from the Ancient Lands series, evoking the serpent's transformative journey through vivid hues and intricate designs that bridge cultural heritage with numismatic artistry.

This PNC is more than a collectible—it's a portal to Australia's profound Dreamtime narratives, where the Rainbow Serpent's fury and benevolence shaped the very earth we tread. Crafted in gleaming copper-nickel and presented with elegant foiling that highlights the commemorative postmark, title, and unique numbering, this piece arrives ready to grace any philatelic or numismatic display. Issued on 5 November 2025 and available until 31 December 2026, it offers collectors a rare opportunity to own a slice of history that intertwines postal heritage, literary milestone, and Indigenous lore, all while supporting the ongoing celebration of Australia's diverse cultural tapestry.
