100 Dollars - Elizabeth II Red-bellied Black Snake

Niue has operated as a prolific licensing hub for commemorative bullion since the 1990s, contracting Perth Mint and others to strike coins under its nominal authority while the island itself — population under 2,000 — conducts virtually no independent monetary policy. The red-bellied black snake series falls squarely into this commercial bullion framework, where sovereign branding is essentially leased.

The species itself is endemic to eastern Australia, where it accounts for a significant share of recorded snakebites annually despite a venom potency lower than many of its relatives.
