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:
The mysterious cat-burglar of Gotham City, as seen in the 2022 film, The Batman, has managed to slink her way onto this 1oz pure silver Chibi Coin!
Superbly shaped and coloured, this piece features Catwoman wearing her cut-out mask, iconic leather catsuit, black boots and holding her signature whip. To give a 3D look, some relief has been added, further enhancing the design. The obverse displays the effigy of Queen Elizabeth ll, confirming it as legal tender.
Created in partnership with Warner Bros. Consumer Products, each piece arrives in a quality box with The Batman-themed imagery. A large window on the front ensures you can easily display it in your collection. To protect your coin from the dangers of Gotham City, it’s held in a clear acrylic capsule. On the back, you’ll find a Certificate of Authenticity and the coin’s unique number in its limited mintage of 2,000. |
