1 Gulden

The Curaçaosche Bank was established in 1828 as the issuing authority for the Dutch Caribbean colonies, and by the early twentieth century it served not just Curaçao but the broader Netherlands Antilles group. These small-denomination gulden notes from the 1903–1918 period circulated in an economy still largely driven by the transit trade and salt extraction — oil refining would not transform the island until the Shell refinery opened in 1918.

Pick 7A is among the scarcer issues from this bank, with surviving examples in any grade relatively uncommon, likely reflecting both heavy use and the tropics' predictable effect on paper stock.
