1 Dollar - Charles III Bluebottle

Tuvalu has issued wildlife-themed bullion and collector coinage under licensing arrangements with the Perth Mint for decades, with the Australian facility handling striking, distribution, and assay guarantees on behalf of the Pacific island nation. The Bluebottle — Physalia utriculus — is technically not a jellyfish but a colonial siphonophore, a single organism composed of genetically identical but functionally specialized zooids.

Perth Mint struck this as part of a broader marine series. The .9999 fineness is characteristic of that facility's output since the 1990s, when it moved to four-nines purity to compete directly with Canadian and Austrian bullion programs.
