1 Dollar - Elizabeth II Marlin, Silver

The Cayman Islands have issued collector silver rounds under royal authority since the 1970s, but this series occupies a specific niche: legal tender bullion coinage from a British Overseas Territory that maintains its own currency — the Cayman Islands dollar, pegged at 1.20 USD — entirely independent of sterling. The blue marlin holds particular local significance; the islands host one of the Atlantic's most-attended sportfishing tournaments, the Million Dollar Month, running annually since 1998.

KM#165.1 spans a four-year date range, meaning examples can vary by year without affecting the type designation.
