New Zealand uses the New Zealand Dollar as its circulation currency for daily transactions. The country also issues a number of commemorative and collector coins, including in the large two ounces of silver format (abbreviated as 2 oz Ag, where "Ag" comes from the Latin word for silver, Argentum). Authorised by the Reserve Bank of New Zealand, the official issuer of these coins is NZ Post - which also issues the country's postal stamps. Manufacturing of the coins is commissioned to various foreign mints.
The coins are "Non-Circulating Legal Tender" (NCLT) and not bullion because they are issued at prices much higher than their intrinsic value and are targeted at collectors who appreciate them for their artistic or sentimental value, and not at bullion investors.
This silver coin was issued to celebrate the 75th Birthday of King Charles III. It features an obverse with a portrait of the king developed especially for New Zealand.
NZ Post says about the coin:
On 14 November 2023 His Majesty King Charles III will celebrate his 75th birthday. Born at 9:14pm on 14 November 1948 weighing 7lb 6oz, Charles Philip Arthur George is the first-born son of Her Late Majesty Queen Elizabeth II and His Late Royal Highness Prince Phillip, Duke of Edinburgh.
Traditionally, British monarchs have celebrated their birthdays twice a year. Each year, Aotearoa New Zealand observes King’s Birthday as a public holiday (formerly Queen’s Birthday). The commemoration of the monarch’s birthday is always observed in June, when New Zealanders are treated to a winter break thanks to the timing of the holiday in the northern hemisphere. |
