The coin’s reverse depicts the Welcome Stranger, the largest nugget ever recorded. Unearthed by prospectors John Deason and Richard Oates at Moliagul, Victoria in February 1869, their 2,284 ounces find was too large for the scales and had to be broken into three pieces before being weighed. The portrayal of the nugget and the outer rim is gilded in 24-carat gold. The nugget is surrounded by a line drawing of the map of Australia and encircled by a ring of stylised sun rays. Within the design is the nugget’s name, and a ‘P40’ mintmark. Also included on the reverse is the inscription ‘THE AUSTRALIAN NUGGET’, together with the weight, purity and 2026 year-date.
