1 Peso Plata Boliviana

Banco del Comercio was one of the provincial free-banking era institutions that briefly flourished in the Argentine littoral before federal banking legislation ended the experiment. Gualeguay, a river port in Entre Ríos province, had sufficient commercial activity — largely tied to cattle and cowhide export — to support a local note-issuing bank, though for how long the bank actually operated and how widely these notes circulated remains poorly documented.

The PS prefix in the Pick reference signals this is catalogued among speciman or doubtful issuers — survival rate is extremely low, and whether notes of this series ever reached general circulation is an open question.
