10 Dollars - Elizabeth II Seaplane, Colourized

The Eastern Caribbean Central Bank issues commemorative gold almost exclusively through licensing arrangements with third-party minting programs — this piece originates in that framework, tied to the broader push by ECCB member states to generate numismatic revenue rather than circulating coinage. The seaplane subject connects to the interisland air services that replaced much of the region's earlier dependence on mail boats and inter-island schooners.

Applied colour on .9999 gold is an enamel or resin process done post-strike, typically at the mint or under contract. It does not affect metallic content but affects resale in some collector markets.
