10 Dollars - Elizabeth II Coat of Arms, Colored

The Eastern Caribbean Central Bank, which manages monetary policy for eight island states through a currency union established in 1983, rarely issues gold. When it does, the pieces are almost invariably bullion-adjacent collector issues with limited distribution outside specialist channels — this 2022 colored gold piece being no exception. The ECCB's parent organization traces back to the British Caribbean Currency Board of 1950, which itself replaced a patchwork of colonial monetary arrangements that had persisted since the 18th century.
