10 Libres Project for Mercosur Common Currency

Never issued, never circulated. This note was produced as a design proposal during a period when Mercosur economists were actively debating a regional common currency — tentatively named the "Gaucho" in some discussions, though the "Libre" denomination used here reflects a competing nomenclature that briefly gained traction. The project stalled almost immediately against the structural reality that Brazil and Argentina could not agree on a common monetary framework, and no central bank with this name has ever been formally constituted.

Nascimento's involvement places this firmly in the Brazilian design tradition for the proposal — though the note remains a speculative artifact, not an official state commission.
