200 Pesos

The Junta de la Administración de la Casa de Moneda was not a central bank in any modern sense — it was a monetary board managing the Buenos Aires mint and its paper emissions during a period when the province operated its own currency entirely independent of other Argentine territories. By 1848, the Buenos Aires peso papel had been depreciating for years under the fiscal pressures of the Rosas government, and high-denomination notes like this 200 Pesos were a direct consequence of that inflation eating into the note's practical purchasing power.

The PS prefix in the Pick catalog indicates provincial or quasi-governmental status — this was never a national emission.
