1 Dollar - Elizabeth II 4th Portrait - 30 Years Mob of Roos

The original mob-of-kangaroos reverse was introduced in 1984 when Australia switched from the pre-decimal-era wildlife coins to a dedicated circulation dollar. Stuart Devlin designed it, and the composition of that first run was actually aluminium-bronze — the copper-nickel used here came later. This 2014 commemorative marks three decades of that design's uninterrupted presence on the circulating dollar, making it one of the longest-running reverse designs in modern Australian coinage.

The pad-printing technique applied to this piece — a process borrowed from industrial product marking — allows color or surface detailing beyond what standard striking achieves, and the RAM began deploying it seriously on collector issues around this period.
