Spanish colonial reales circulated alone until 1813, when Argentina began issuing its own coins.
Silver coins were issued in the name of the "Río de la Plata Province" in denominations of 1⁄2, 1, 2, 4 and 8 reales and 1⁄2, 1, 2, 4 and 8 soles, whilst gold coins (87.5%) were issued in denomination of 1, 2, 4 and 8 escudos.
Other provinces issued coins denominated in reales (silver) and escudos (gold): Córdoba, Entre Ríos, La Rioja, Mendoza, Salta, Santiago del Estero and Tucumán.
In 1820, the Government of the Province of Buenos Aires introduced notes in denominations of 5, 10, 20, 40, 50 and 100 pesos.
The Banco de Buenos Ayres began issuing notes in 1822 in denominations of 20, 50, 100, 200, 500 and 1000 pesos.
