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.
The Mint says about this coin:
Commander William T. Riker is seen with his trademark beard and wearing the red Command Division Starfleet uniform. This 1oz silver coin has been shaped and coloured to resemble the authoritative figure. Slight relief has been added to the design to give a more realistic effect. Engraved on the obverse is the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth ll, to confirm it as legal tender.
Each officially licensed coin arrives in an acrylic case to ensure protection. It is then held inside a Star Trek-themed box that features striking images of the characters and a window to easily display your piece to the universe. Printed on the back of the box is a Certificate of Authenticity, the coin’s specifications, and the unique number of the coin in the limited mintage of 2,000. |
