10 Dollars - Elizabeth II Pink Flamingos, Colourized

The Eastern Caribbean Central Bank issues collector gold almost exclusively through licensing arrangements with private minting firms — in this case, the colourized flamingo series was produced for the numismatic market with no intent of circulation. The ECCB's circulating coinage serves eight member territories, but its bullion and commemorative program exists largely as a revenue mechanism, selling to foreign collectors rather than regional economies.

Flamingos have a genuine Caribbean presence, with significant breeding populations in the Bahamas and on Bonaire — though neither is an ECCB member state.
