50 Caribbean Guilder Banknote (Green Sea Turtle)

50 Caribische Gulden Caribbean Gulden (Issued 2025)

Issued on 31 maart 2025 by the Centrale Bank van Curaçao en Sint Maarten, the 50 Caribische Gulden note of the ‘World Under the Sea’ series represents the inaugural printed currency for the newly unified monetary union of Curaçao and Sint Maarten — a landmark moment in Caribbean monetary history that any serious banknote specialist would immediately recognise. The note’s dominant aquatic theme, rendered in a sophisticated palette of greens, yellows, and teals, signals a deliberate departure from portrait-based traditions in favour of a rich natural heritage narrative. The centrepiece illustration of a green sea turtle, identified on the note itself by the annotation “groene zeeschildpad”, gives this denomination an immediately striking visual identity. For those seeking to exchange Caribbean Gulden notes in the UK, the 2025 issue is the current, valid series in circulation.

On the front, the note is dominated by a highly detailed, naturalistically rendered green sea turtle (groene zeeschildpad) positioned centrally and occupying much of the note’s face, its shell and flippers rendered with fine engraving-style linework that captures the texture of the creature’s scutes and skin against a luminous aquatic background. The background blends soft yellow-green and pale teal tones, evoking shallow Caribbean waters, with subtle guilloché patterning and delicate underwater motifs — including what appear to be stylised coral and small fish — visible in the background field to the right of the turtle. At the upper left, the denomination text reads “VIJFTIG” in bold, dark green capital letters, with “CARIBISCHE GULDEN” printed beneath in a slightly smaller but equally prominent typeface. A large numeral “50” appears in the upper right corner in deep green, and a second, smaller “50” numeral is incorporated into an oval holographic or colour-shifting security element on the left side, which features a spiralling shell motif rendered in iridescent green tones. To the far left, a vertical security strip in teal is visible, bearing the text “WETTIG BETAALMIDDEL” printed vertically, alongside further shell imagery. Two facsimile signatures appear in the lower central area, one beneath the title “PRESIDENT” and one beneath “DIRECTEUR-SECRETARIS”, in flowing handwritten style. The issuing authority, “CENTRALE BANK VAN CURAÇAO EN SINT MAARTEN”, is printed in bold dark green text at the lower right of the note.

The reverse presents an idyllic coastal scene identified by the caption “Grote Knip, Curaçao” — a well-known beach on the western coast of Curaçao — depicted in a scenic, full-colour illustration showing a sweeping bay with turquoise-blue water, a pale sandy beach lined with beach umbrellas and trees, and lush green hillside vegetation rising in the background. Coral elements in warm orange-red tones frame the lower foreground, and two stylised fish in green and teal swim across the lower portion of the scene, consistent with the series’ underwater marine theme. The serial number “U31 4141137” is printed vertically in black on both the left and right edges. A large numeral “50” appears in dark green at the upper left, while the text “CENTRALE BANK VAN CURAÇAO EN SINT MAARTEN” runs vertically in bold green type along the upper right edge. The denomination text “VIJFTIG CARIBISCHE GULDEN” is printed in large, bold dark green capitals at the lower left. The issue date “31 maart 2025” is clearly printed in small text near the top centre of the note, and the copyright line “auteursrecht Centrale Bank van Curaçao en Sint Maarten” runs along the very bottom edge. A green guilloché-patterned band is visible near the top of the reverse, with light yellow-green tones forming the overall background field.
