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. Many of them are in standard bullion sizes - typically, one ounce of silver (abbreviated as 1 oz Ag, where "Ag" comes from the Latin word for silver, Argentum). Many of these feature famous movie characters.
This coin is part of the New Zealand Mint's Guards Of The Empire coin series dedicated to characters from the Star Wars films.
The Mint says about it:
"The Knights of Ren, elite, fearsome enforcers of Kylo Ren's dark will, feature in our officially licensed Guards of the Empire Silver Coin Collection. The coin shows one Knight, Vicrul, in full colour holding his vicious ultrasonic scythe. The detailed, engraved background shows the rest of the masked Knights along with their leader Kylo Ren.
This rectangular, 1oz pure silver legal tender coin incorporates the Ian Rank Broadley effigy of Her Majesty Queen Elizabeth II and an antique finish to add to the menacing feel. Packaged in a Star Wars branded box, the coin is placed inside an acrylic holder which is ideal for displaying this precious limited-edition treasure. A Certificate of Authenticity is also included inside the box to confirm the metal purity of the coin and its unique number in the 2,000-coin mintage." |
