25 Rupiah

The "Emergency Issue" designation here is literal. By mid-1948, the Dutch military offensive — the first "Politionele Actie" of July 1947 — had fractured Republican-held territory into isolated pockets, and central printing and distribution were practically impossible. Regional and local authorities issued their own currency out of necessity, which is why notes under the S-prefix series (S for "specialized" in Pick's classification) vary significantly in production quality and security features compared to the Jakarta-issued Republican notes.

Printed domestically under wartime constraints, paper quality and ink consistency are notoriously uneven across surviving examples — this is a known characteristic of the type, not a sign of damage or cleaning.
