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 famous movie characters.
This coin is part of a New Zealand Mint series dedicated to the Star Wars movies and features the famous Death Star.
The Mint says about it:
"This terrifying weapon, the Death Star™, looks magnificent on this finely engraved 1oz silver coin officially licensed by Lucasfilm. The coin arrives in a Star Wars™ themed box." |
