10 Pesos Plata Corriente Boliviana

The Banco de San Juan was a Bolivian-chartered bank operating branches across the Argentine northwest during the 1870s — an arrangement that made legal and commercial sense at the time, given the deep mercantile ties between the Andean provinces and Bolivia, but which placed the issuing authority in a peculiar regulatory limbo relative to Argentine federal banking law. The Catamarca branch was one of several such outposts extending the bank's note circulation into territories where local banking infrastructure was almost nonexistent.

Guillermo Kraft was among the most active commercial printers in Buenos Aires during this period, handling a wide range of provincial and foreign-chartered bank issues. The incomplete date ("187_") indicates the final digit was to be filled in at the branch level upon issue — a common practice that also makes precise dating of surviving examples impossible without additional provenance.
