50 Dollars Charles III Kenn Reef

The Coral Sea Islands Territory is one of Australia's most obscure external territories — an uninhabited scattering of reefs and cays administered from Canberra with no permanent civilian population, making any coinage issued under its name a legal curiosity rather than a circulating currency. Kenn Reef sits near the eastern edge of the territory, roughly 800 kilometres off the Queensland coast.

The "Paper coloured" designation refers to a production method where the coin surface is treated to replicate the texture and palette of banknote printing — a technique used almost exclusively in the modern collectibles trade.
