A 25 sen note from Bank Indonesia's 1964 sen series, printed by P.N. Pertjetakan Kebajoran. One side shows a soldier in a peaked cap wearing a 'Sukarelawan' (volunteer) badge, with the value written as 'Dua Puluh Lima Sen'. The other side carries a large rosette and the numeral 25 in red guilloche patterns. The volunteer theme of this series reflects the mobilisation campaigns of President Sukarno's government in the mid-1960s.
