10 Dollars Discovery of the New World, silver proof

Part of a broader commemorative program anticipating the 1992 quincentenary of Columbus's first landfall, Jamaica began issuing New World Discovery coins years ahead of the anniversary — positioning itself among the earliest Caribbean issuers to stake a claim on the occasion. The Bank of Jamaica's timing was deliberate; by 1989 the numismatic market for Columbus-themed issues was already crowded, and early entry mattered commercially.

KM#140a designates the silver proof variant, distinguished from the base-metal circulation strike by composition alone.
