10 Dollars Victoria, Gold Proof Issue

The Eastern Caribbean Central Bank, which manages the common currency of eight island territories, rarely issued gold coinage — this 2002 proof belongs to a small program tied to the Queen's Golden Jubilee, which prompted commemorative issues across dozens of Commonwealth mints simultaneously. The ECCB's participation was notable given that gold coins have never circulated in the Eastern Caribbean Currency Union; this was purely a collector instrument from inception.

At just over 39 grams of 22-karat gold, the specification mirrors the traditional British sovereign weight standard — a deliberate nod to the monetary architecture the region inherited from colonial administration.
