3 Pesos metálicos

The Provincia de Buenos Aires began issuing paper currency in 1822 through the newly created Banco de la Provincia de Buenos Aires — one of the earliest provincial banking experiments in post-independence South America. These early peso metálico notes were nominally convertible to silver, a promise that collapsed well before mid-century as the province's finances deteriorated under successive military and political crises.

Printed locally rather than contracted to a European house, the production quality reflects the limited infrastructure available in Buenos Aires at the time. Juan Manuel de Luca's single signature is consistent with the authorization structure of the early series.
