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 internationally popular one ounce of silver format (abbreviated as 1 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 coin commemorates the Royal Wedding of Prince Harry and Meghan Markle.
NZ Post says about it:
The coin design reflects the close relationship that New Zealand has with the monarchy, as a Commonwealth nation. The centre of the coin features a printed image of the happily engaged couple. Surrounding the royal couple is a heart-shaped koru pattern and two red roses which are symbolic of each Harry (English rose) and Meghan (US rose). |
