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 is the first issue in a New Zealand Mint series of Chibi coins featuring Marvel characters, and is dedicated to Ant-Man.
The mint says about it:
The size-changing Super Hero, Ant-Man features on this first 1oz pure silver Chibi Coin for Marvel! Officially licensed, this splendid piece is shaped and coloured to show him in his black and red suit. The design includes some relief which gives an awesome 3D effect.
Despite its uniqueness, the coin is legal tender, with the Public Seal of Niue engraved on the obverse. Each coin is packaged inside a custom-designed box, that is surrounded by epic character imagery. The large window allows you to easily display your collectible. Turn to the back, and you will find a Certificate of Authenticity, including its unique serial number in the mintage.
One in ten coins (distributed randomly) is gold plated. |
