The guilder (Dutch: gulden) is the currency of two of the five islands which until 2010 formed the Netherlands Antilles. It is subdivided into 100 cents (Dutch plural form: centen). The guilder was replaced by the US dollar on 1 January 2011 on the other former islands of the Netherlands Antilles: Bonaire, Saba and Sint Eustatius. On Curaçao and Sint Maarten, the Netherlands Antillean guilder will be replaced by the newly created Caribbean guilder.
