The Tesorería General de la República Argentina occupied an unusual institutional position — it was a state treasury office, not a central bank, issuing fiduciary currency during a period when Buenos Aires province and the Argentine Confederation were still operating as effectively separate monetary zones. The 1860 date places this note shortly after the Battle of Cepeda (1859) and the Pact of San José de Flores, which nominally reunified the country but left the banking and currency arrangements deeply unsettled for years afterward.

PS# prefix in the Pick catalogue denotes provincial or state issue rather than a national banking authority — important for attribution, since several Argentine institutions of this period issued circulating paper that is frequently misidentified.
