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.
Cuban convertible peso
When U.S. banknotes are exchanged, a 10% tax is applied, plus an exchange commission. The 10% tax is not applied to other currencies; hence, American visitors may benefit by first changing their money into euros, Canadian dollars, or other hard currencies before they convert them to pesos, although such a benefit would depend on the rate at which they can get the third currency. (Some U.S. banks charge exchange margins of 10% or more.)
