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.
Cook Islands dollar
The Cook Islands has a long reputation for frequent monetary oddities. It was one of the last countries to hold on to large crown-sized coins while elsewhere, coins of such size are seldom ever minted in large enough quantities intended for circulation. In 1987, with the release of its new $2 piece, Cook Islands officially became the first modern country to issue a circulating three-sided coin, as well as one of only a handful of countries at the time with a widely circulating $5 piece. 1988 brought the redesign of the 50-cent piece, quite unique in becoming the first coin in the country to bear a denomination name. Although widely recognized as "cents" this coin depicts "tene", the native language equivalent to the English word cent. It also abandoned its 1 and 2-cent pieces almost 10 years before both New Zealand and Australia, only to bring the 1 cent back 20 years later. It also replaced $1 and $2 notes for coins two years before New Zealand did, even though the Cook Islands dollar is pegged to the NZD at par. Amidst minting $2 and $5 coins, it also issued an oddball $3 note in between the dollar coins as part of the same series.
