25 Gulden

De Javasche Bank, established by royal charter in Batavia in 1828, held the monopoly on note issue in the Dutch East Indies throughout this period. The 25 Gulden denomination sat at the practical upper end of everyday commercial use — sufficient for wholesale trade settlements in the colony's commodity markets, particularly sugar and rubber, which were at the center of a severe price collapse by the early 1930s.

Joh. Enschedé en Zonen had printed Dutch colonial currency for generations from their Haarlem works, and the quality of intaglio work on this series reflects that long relationship. Cotton substrate and a watermark were the primary security measures — modest by contemporary European standards, but counterfeiting in the Indies was a persistent enough problem that the bank periodically withdrew and reissued denominations on short cycles.

The 1931 end date for this issue coincides with the Netherlands abandoning the gold standard.
