100 Dollars - Elizabeth II Churchill

Issued the year before the Cayman Islands gained a new constitution formalizing greater autonomy from Britain, this gold piece commemorates Churchill at a moment when the islands were still consolidating their identity as a distinct Crown dependency. The .500 fineness is notably low for a commemorative gold issue of this period — most Commonwealth gold commemoratives of the early 1970s were struck in .900 or better — and almost certainly reflects a cost-control decision by the issuing authority rather than any metallurgical tradition.
