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 characters and themes from popular culture.
This coloured rectangular coin features the Stag Patronus from Harry Potter.
Harry Potter is a series of seven fantasy novels by J.K Rowling following the life of young wizard Harry and his friends as they navigate the wizarding world and the rising evil of Lord Voldemort.
The Patronus is the most famous defensive charm in the wizarding world. Producing a silver-white guardian taking the form of an animal, it is the only effective spell used against Dementors and each patronus has its own symbolic meaning drawn from one’s true self. Harry’s patronus manifests itself in the form of a stag, a symbol of rebirth and resurrection, similarly to his parents patronus’ (a doe for his mother and stag for his father) who both died trying to protect him. |
