1 Rupiah Serang, Banten Residency

Banten Residency's 1947 emergency issues belong to the chaotic interim period of Indonesian independence, when the Dutch were reasserting control through military action and central banking had effectively collapsed across much of Java. Local civilian administrations — residencies, municipalities, even individual districts — filled the vacuum by issuing their own currency, typically under explicit authorization from the Republican government in Yogyakarta but with wildly inconsistent production standards.

The Serang designation refers to the residency capital, not a separate issuing authority. These notes circulated alongside a half-dozen other local issues and were formally demonetized once Bank Indonesia consolidated Republican currency after 1949. Survivors tend to show heavy use.
