50 Dollars - Elizabeth II House of York

Issued to mark the 25th anniversary of Queen Elizabeth II's coronation — which the Cayman Islands commemorated a year late, in 1979–1980 — this piece belongs to a wave of Commonwealth gold issues that flooded the market in that period, many struck in debased alloys to keep prices accessible. At .500 fineness, the gold content sits just above the threshold that separates numismatic novelty from meaningful bullion value, a compromise typical of the Caribbean commemorative issues produced by the Franklin Mint and similar contractors for small jurisdictions with no minting infrastructure of their own.
