2 Dollars - Elizabeth II Emerald Isle of the Caribbean, Colored

The Eastern Caribbean Central Bank issues currency on behalf of eight territories, most of which are independent states within the Commonwealth — Antigua and Barbuda, Dominica, Grenada, St. Kitts and Nevis, St. Lucia, and St. Vincent among them. This 2018 collector piece falls under the ECCB's long-running commemorative program, which has leaned heavily on regional identity marketing since the early 2000s as a revenue stream separate from its circulating coinage mandate. The applied color process involves a resin or lacquer overlay fired after striking, a technique that attracts collector premiums but raises long-term preservation questions that straight-silver issues don't face.
