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.
Mauritian dollar
In 1820, in response to a request from the British colony of Mauritius, the imperial government in London struck silver coins in the denominations of , , and dollars. The dollar unit in question was equivalent to the Spanish dollar and these fractional coins were known as 'Anchor Dollars' because of the anchor that appeared on them. More of these anchor dollars were struck in 1822 and not only for Mauritius but also for the British West Indies. In addition to this, a dollar anchor coin was struck for Mauritius. A year or two later, copper dollar fractions were struck for Mauritius, the British West Indies, and Sierra Leone.
