500 Pesos

The Banco y Casa de Moneda del Estado de Buenos Ayres was a creature of provincial politics — Buenos Aires had seceded from the Argentine Confederation in 1852 following the battle of Caseros, and for nearly a decade the province operated as an independent state with its own currency, customs revenue, and banking apparatus. This note belongs to that interregnum period, when Buenos Aires peso notes were legal tender within the province but explicitly excluded from the rest of the territory that would later become the Argentine nation.

High-denomination provincial paper from this period is rarely encountered in collectible condition. The Buenos Aires monetary system collapsed under inflation well before reunification in 1861, and most surviving paper from the Casa de Moneda suffered accordingly.
