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 second coin in the Endangered Animal Species series and features the Siberian Tiger.
The Mint says about it:
"The eye-catching reverse displays two coloured Siberian Tigers as well as the map showing their natural habitat. The magnifying glass is embellished with an orange Swarovski crystal. Known as the largest of all tigers, the Siberian Tiger can grow up to 4 m in length and weigh up to 350 kg. It has got beautifully coloured thick fur to keep it warm during bitter Siberian winters. Unfortunately, the animals are now considered as a critically endangered species - no more than 450 tigers inhabit the Sikhote-Alin mountain range east of the Amur River, Russia." |
