20 Pesos

The Junta de la Administración de la Casa de Moneda was the issuing arm of the Buenos Aires mint during the Rosas period — a time when the province's paper currency had long since abandoned any pretense of convertibility. The inconvertible peso corriente had been the de facto standard since the early 1820s banking experiments collapsed, and by 1844 these notes were functioning in a chronic inflationary environment with no metallic backing whatsoever.

PS#387 is among the more elusive issues in the Buenos Aires provincial series. Locally printed materials from this period were produced under considerable technical constraints, and survival rates are low.
