Issued to mark the 1975 observance of Columbus's 1494 landfall on Jamaica, this was part of a broader Caribbean commemorative movement that followed Jamaica's 1962 independence — newly sovereign nations using coinage to assert historical narratives on their own terms. The Bank of Jamaica struck both a silver proof and a cupro-nickel circulation version; the .925 silver proof was aimed squarely at the international collector market then hungry for Commonwealth-adjacent issues.
KM#66a distinguishes the silver proof from the base-metal 66, a split that Krause records cleanly but which dealers occasionally conflate in bulk lots.
