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 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 - such as one ounce of gold (abbreviated as 1 oz Au, where "Au" comes from the Latin word for gold, Aurum).
Downies says about this coin:
Splash out on a masterpiece that’s more art than coin! This Niue legal tender stunner masterfully depicts the vibrant fighting fish (also known as betta fish) in fin-tastic proof perfection. This feisty fish is known for its bright, beautiful coloration and elaborate fin displays. First discovered in Southeast Asia, fiercely territorial and wildly beautiful, these underwater warriors move in a mesmerising kaleidoscope of colour, captured in digital colour on the reverse of the 2024 $100 Siamese Fighting Fish 1oz Gold Proof Coin.
The blue and pink shades of the fins of two Siamese fighting fish ripple and swirl across 1oz of pure 99.99% gold, creating a wonderful sense of movement and iridescent shimmer. |
