200 Pesos

The Banco y Casa de Moneda del Estado de Buenos Ayres operated during the brief but consequential period when Buenos Aires province functioned as a separate political entity from the Argentine Confederation — the secession lasted from 1852 to 1861. Notes issued during this window carry the provincial rather than national authority, a distinction that matters for attribution. The "Casa de Moneda" component of the issuer name reflects the institution's dual mandate: both currency emission and mint operations fell under a single roof.

At 200 pesos, this sits near the top of the denomination range for the series — a face value that kept it largely out of everyday retail exchange and in mercantile or government transaction use.
