200 Pesos

The Casa de Moneda in Buenos Aires had been functioning as the province's de facto central bank since the 1820s, issuing notes that circulated provincially rather than nationally — Argentina had no unified currency until 1826, and even then the experiment collapsed quickly. By 1841, the institution was operating under the Rosas administration, and paper peso emissions were already deeply inflationary; the province had been running on inconvertible paper since 1826 when specie payments were suspended and never meaningfully restored.

Printed locally rather than by a European firm, which was still unusual for South American issues of this period. Survival rate is extremely low.
