1 Peso Plata Boliviana

San Luis was one of the smaller Argentine interior provinces that issued its own fractional currency during the 1870s, a period when federal coinage was chronically scarce in the interior and provincial governments stepped in with paper substitutes denominated in the old boliviano silver unit — a colonial accounting convention that persisted in everyday commerce long after Bolivia itself had moved on. The denomination "Peso Plata Boliviana" reflects that regional habit rather than any formal monetary tie to Bolivia.

L.D. H. Sisson was a Buenos Aires-based printer active in producing provincial fiscal and currency paper during this period. PS#1395 is among the rarer provincial emissions from this era; San Luis had a small economy and limited issuance, and survival rates for these notes are low.
