60 Gulden

The 60 Gulden denomination is a peculiarity of Dutch banking practice — most European central banks settled on round decimal series, but De Nederlandsche Bank maintained 60 Gulden notes well into the twentieth century, a holdover from older accounting conventions rooted in the 60-stuiver guilder calculation system. By the time this series closed in 1921, the denomination had become genuinely anachronistic, and no successor note replaced it.

The sixty-year issuance window masked considerable variation: serial numbering, signature combinations, and paper stock changed multiple times across the run, and distinguishing early 1860s examples from later printings requires close attention to the cashier countersignatures.
