10 Dollars - Elizabeth II Diving Paradise

The Eastern Caribbean Central Bank issues legal tender coinage on behalf of eight member territories — Antigua and Barbuda, Dominica, Grenada, Montserrat, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, and Anguilla — none of which operate independent central banks. This "Diving Paradise" issue belongs to a bullion and collector series exploiting the region's reef tourism identity for export numismatic revenue rather than domestic circulation. The ECCB has leaned heavily on these themed issues since the 2010s as a revenue mechanism, with actual circulation of gold coinage essentially nonexistent across the member states.
