2 Dollars - Elizabeth II Sisserou Parrot

The Eastern Caribbean Central Bank serves eight island territories under a single currency union — one of the few functioning multi-jurisdictional monetary arrangements in the Western Hemisphere. This particular issue highlights Dominica's national bird, the Sisserou parrot, a species so critically endangered that the wild population is estimated at fewer than 350 individuals. Its appearance on coinage predates this 2019 release by decades, having featured on Dominican currency since the territory's earliest post-independence issues.

The .999 silver format at 31.1g places this squarely in the modern bullion-adjacent commemorative market rather than any circulation context.
