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 - for example, two ounces of silver (abbreviated as 2 oz Ag, where "Ag" comes from the Latin word for silver, Argentum).
This coin is part of The Punk Universe series, and features Silkpunk.
The mint says about it:
The term Silkpunk describes a genre of a mixture of science fiction and fantasy that draws inspiration from ancient East Asia. It focuses on technologies and devices made from natural materials of historical significance to East Asian and Pacific Islanders, such as bamboo, shell, coral, paper or silk. It is based on bionics - the science of imitating the way nature behaves and functions - and aims to construct better machines or materials by using solutions created by nature during millions of years of evolution. |
