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 movie characters. Some are also in innovative shapes, such as "Chibi".
Chibi (ちび or チビ) is a Japanese slang word describing something short (a thing, an animal or a person). The term is widely used to describe a specific style of caricature where characters are drawn in an exaggerated way: small and chubby, with stubby limbs and oversized heads. Coins of this type look like cartoon characters and have their corresponding shape; they are also very thick for their size.
This coin features Lord Voldemort, a character from the Harry Potter books and movies.
The Mint says about it:
"The officially licensed Harry Potter™ Chibi™ Coin Collection now includes the powerful Dark Lord and enemy of Harry Potter, Lord Voldemort™. This 1oz pure silver coin has been shaped and coloured to resemble He Who Must Not Be Named in the Chibi art style.
The Ian Rank Broadley effigy of Her Majesty Queen Elizabeth II on the obverse of the coin confirms it as certified legal tender.
A holographic sticker placed on the box, alongside the Certificate of Authenticity, states the coin’s unique serial number in the limited 2,000 mintage. Inside the Harry Potter-themed box, the coin is protected by a custom-made case that fits its unique shape. The large window in the box means it is display-ready." |
