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.
Trinidad and Tobago dollar
From 1949, with the introduction of the British West Indies dollar, the currency of Trinidad and Tobago became officially tied up with that of the British Eastern Caribbean territories in general. The British sterling coinage was eventually replaced by a new decimal coinage in 1955, with the new cent being equal to one half of the old penny. In 1951, notes of the British Caribbean Territories, Eastern Group, were introduced, replacing Trinidad and Tobago's own notes. In 1955, coins were introduced when the dollar was decimalized. In 1964, Trinidad and Tobago introduced its own dollar. Between 1964 and 1968 the Trinidad and Tobago dollar was utilized in Grenada as legal tender until that country rejoined the common currency arrangements of the East Caribbean dollar. The Trinidad and Tobago dollar and the Eastern Caribbean dollar were the last two currencies in the world to retain the old rating of one pound equals four dollars and eighty cents, as per the gold sovereign to the Pieces of eight. Both of these currencies ended this relationship within a few weeks of each other in 1976.
