Niue, a sovereign state in free association with New Zealand, uses two official legal tender currencies. The New Zealand Dollar is the circulation currency for daily transactions, while the government also authorises legal tender coins in the Niue Dollar currency for collector's purposes.
A number of mints issue a large variety of commemorative, bullion and collector coins under the authority of Niue. These coins are dedicated to historical or general popular culture themes not related to Niue itself.
Some coins are marketed in standard bullion sizes, like half ounce silver, one ounce silver etc, and some of those are also denominated as $1, for which see respective lists. This coin, denominated as One Niue Dollar, is not in a standard ounce-based size and is made using a "smartminting" technique - meaning that it has features not generally found in circulation coins.
This is the first coin in the Endangered Animal Species series and features the Hyacinth Macaw.
The Mint says about it:
"Beautifully designed, featuring one of the most splendid birds of the world, this innovative coin of Niue is sure to generate a great deal of demand among collectors. Issued as part of the Endangered Animal Species series, the coin is a unique piece of art with the limited mintage of a mere 2,000 pieces worldwide.
The eye-catching reverse displays two coloured Hyacinth Macaw birds as well as the map showing their natural habitat. The magnifying glass is embellished with a blue Swarovski crystal.
Known as the largest of all parrots, the Hyacinth Macaw is an amazing brilliantly coloured bird native to central and eastern South America. It has a large, powerful beak that easily cracks nuts and seeds; its wingspan is enormous - more than 1.20 m! Unfortunately, the parrot is now considered as an endangered species - no more than 5,000 birds inhabit South American rain forests." |
