1 Peso Plata Corriente Boliviana

Banco de San Juan was a provincial Argentine bank operating under the 1863 banking law that allowed individual provinces to charter note-issuing institutions — a system that produced a chaotic patchwork of provincial paper before federal consolidation ended it in the 1890s. This particular note was issued through the bank's Tucumán branch, making it a branch issue of an already provincial institution, one step further removed from any central authority.

The denomination in "Pesos Plata Corriente" is telling. By 1874, the peso fuerte and peso moneda corriente were both in circulation alongside provincial issues, and specifying plata corriente was an attempt to anchor the note's value to silver — a promise Argentine banks of this period were frequently unable to keep.
