1 Guaraní Aluminium Pattern

Paraguay's 1974 aluminum pattern coinage was produced as part of a broader evaluation of lightweight metals following the monetary reforms tied to the country's rapid infrastructure expansion under Stroessner. Patterns of this type rarely progressed to circulation strikes without design or compositional modification, and most were retained by the Banco Central or dispersed to collectors through official channels rather than reaching commerce.

M#76 attribution places this firmly in the pattern series, not a transitional or essai classification — a distinction that affects both provenance and relative scarcity.
