1 Caribbean Guilder - Willem-Alexander

The Caribbean guilder launched on 1 January 2025, replacing the Netherlands Antilles guilder on the islands of Curaçao and Sint Maarten following a currency reform that had been in planning since the dissolution of the Netherlands Antilles as a political entity in 2010. The fifteen-year gap between political dissolution and actual currency replacement reflects the administrative complexity of coordinating a shared monetary authority — the Centrale Bank van Curaçao en Sint Maarten — across two autonomous countries with no formal political union.

Willem-Alexander's effigy appearing on this inaugural series marks the first Caribbean guilder coinage under any monarch.
