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 a New Zealand Mint series dedicated to characters from famous movies, and features Jack Skellington from Disney's The Nightmare Before Christmas.
The Mint says about it:
"Scare is in the air with this rectangular-shaped coin to celebrate Disney’s classic movie Tim Burton’s The Nightmare Before Christmas. Made from 1oz pure silver, it features a classic, coloured image of the main protagonist, Jack Skellington, amid four gravestones. The coin is also antiqued and engraved with spooky details and Halloween icons for further effect.
It is presented in striking book-style packaging which is designed to match and includes a large window - so you can easily display this delightful collectible of the Pumpkin King. The Certificate of Authenticity is printed on the packaging. The book opens to allow the coin to be removed as you’ll want to see the obverse, which includes a swirling design behind the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II.
The coin is legal tender in Niue and carries a mintage of just 3,000." |
