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:
Infamous criminal mastermind, The Riddler flaunts his utilitarian look on a 1oz pure silver Chibi Coin!
Created in partnership with Warner Bros. Consumer Products, this piece has been shaped and coloured to resemble the trickster as seen in the 2022 film, The Batman. He is shown wearing his military jacket, mask and clear glasses and holding the cling wrap he uses to cover his head. Some relief has been added to further enhance the design. On the obverse, is the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth ll, confirming the coin as legal tender.
This villainous piece is held inside an acrylic capsule for protection and nestled in a high-quality box featuring The Batman-themed imagery. A large window on the front ensures you can easily show it off to the vigilante of Gotham City. On the back of the box is a Certificate of Authenticity, the specifications of the coin and its unique number in the limited mintage of 2,000. |
