1 Centesimo Pattern

Uruguay's 1869 coinage reform was driven by the need to replace the chaotic mixture of foreign and provincial currencies still circulating decades after independence. Pattern issues from this period were struck in multiple metals to test designs and present options to the monetary commission — a gold striking of a base-denomination centesimo is precisely the kind of presentation piece produced for official approval rather than circulation. The disconnect between the metal and the denomination is deliberate: gold proofs of minor coins allowed legislators and treasury officials to evaluate design quality under optimal conditions.
