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 Man's Best Friends series and features a Friesian Horse.
The Mint says about it:
"Not only lovers of equestrian activities will be enchanted with the silver gleams of this commemorative coin! Vivid images of the magnificent Friesian horses dynamically reflect the sheer beauty of these gentle animals. Thanks to best-quality digital printing the image of the sable stallion depicted on the coin looks strikingly lifelike. The design of the reverse alludes to the rural landscape of the historical province of Friesland - the cradle of the Friesian horse.
Purebred Friesian horses are recognised by their raven-black coat colour, powerful overall conformation, good bone structure, arched neck and well-chiselled, short-eared head. A Friesian horse has a long thick mane and a silky tail. These beautiful animals are noted for their brisk, high-stepping trot. Friesian horses are valued for their intelligence, docility and willingness to cooperate with people. Elegant and good tempered, Friesian horses are highly valued among film directors, hence their popularity in movies and television. For example, they were starred in such films as The Mask of Zorro and Interview with a Vampire." |
