100 Gulden

De Curaçaosche Bank was established in 1828 as the central issuing authority for the Dutch Caribbean territories, and by the 1920s was producing notes for a colonial economy increasingly shaped by Shell's oil refinery operations on the island, which had opened in 1918 and transformed Curaçao's financial needs almost overnight. The 100 Gulden was a high-denomination instrument in that setting — serious commercial paper, not everyday currency.

Enschedé in Haarlem had been the trusted printer for Dutch colonial currency for generations, and their intaglio work on this series is technically accomplished. The Thielen and Schotborgh signature combination places this note within a narrow window of the bank's administrative history.
