10 Centésimos Pattern

Uruguay's 1976 military government, which had seized power in 1973 after dissolving parliament, oversaw a wholesale redesign of the national coinage series during this period. This aluminium piece is a pattern strike — produced to test the design and alloy before committing to circulation production — and was never released to the public.

KM#PnB108 is one of several aluminium pattern trials from this year, suggesting the mint evaluated multiple alloy options before the final composition decision was made.
