5 Pesos Fuertes

Banco de San Juan was one of several Argentine provincial banks that issued notes under the currency reforms of the 1850s and 1860s, a period when Buenos Aires and the interior provinces were still negotiating the terms of monetary federation. Provincial paper circulated on local trust and was frequently discounted outside its home province — a San Juan 5 Pesos Fuerte was worth considerably less in Rosario or Córdoba than it claimed on its face.

The "Fuertes" denomination distinguished these notes from the heavily inflated Pesos Moneda Corriente, at a fixed rate of 25 to 1.
