Some ideas shine brighter than others. This exclusive seven-coin collection gathers Australia’s most inventive breakthroughs — the stump-jump plough, jaffle maker, black-box flight recorder, baby safety capsule and WLAN technology — each struck with a special lightbulb privy mark that signals pure ingenuity.

At the heart of the set sits the $2 coin featuring all five inventions circling a glowing lightbulb etched with the map of Australia, while one of the $1 Black Box coins arrives in vivid colour. Presented in a bold, contemporary display box, this limited collection of just 15,000 sets is a sparkling tribute to the clever minds that changed the way we farm, travel, communicate and care for our families.
