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 coin is part of the Endangered Animal Species series and features the Mountain Gorilla.
The Mint says about it:
"The Mint of Poland is honoured to announce issuing the sixth coin of the series dedicated to animals which are in danger of going extinct. The coin has been issued in the series designed to remind us, human beings, of the duty of taking the greatest care of all endangered species.
The coin is offered in an offbeat colourful packaging with an outline of animals to be featured in this series. The coin and its packaging are set in a box with an image of a gorilla which has been designed specifically to house this item. This important for the mankind theme has been wonderfully depicted on this coin making it the perfect gift for animal lovers." |
