Caribbean guilder
The Netherlands Antillean guilder will continue to circulate and plans to implement the Caribbean guilder will not be finalized until the islands' Central Bank situation is resolved. The new currency will be abbreviated CMg (for Curacao, Sint Maarten guilder) and would be pegged to the United States dollar at the same exchange rate as the Netherlands Antillean guilder (1 USD = 1.79 NAg = 1.79 CMg). As the BES islands (Bonaire, Sint Eustatius and Saba) adopted the U.S. dollar directly on 1 January 2011, the introduction of the CMg would mean the end of the circulation of the Netherlands Antillean guilder.
Curaçao reaal
Between 1799 and 1815, 12 reaal were equal to a Spanish dollar (8 "reales"). From 1815 until 1828, 15 reaal were equal to a Spanish dollar. Many of the coins were produced from overstamped or cut Spanish or Spanish colonial coins. In 1828, the reaal was replaced by the Dutch gulden at the rate of 3⅓ reaal = 1 gulden.
