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.
This 5g Silver Coin Note is part of a New Zealand Mint series of small silver foils, and is a Christmas card with a Star Wars theme.
The Mint says about it:
The new Star Wars - Season's Greetings Coin Note sends Christmas greetings in form of a 5 g silver coin note. To delight every Star Wars fan on the feast days, this beautiful coin note features several characters from the legendary saga - Princess Leia, Luke Skywalker, Han Solo and Chewbacca. They are standing behind a richly decorated Christmas garland, singing Christmas songs in full voice. Look closely and you will see unique Star Wars-themed baubles engraved in the background.
The coin note is inside a special holder, which is designed like a Christmas card. Inside the coin note is an illustration of Chewbacca with a gift, accompanied by the humorous words "Arrrrrrgh! Socks again". |
