The Cook Islands, a sovereign state in free association with New Zealand, uses two official legal tender currencies. The New Zealand Dollar circulates in parallel with the local Cook Islands Dollar; at the same time, the government also authorises many legal tender coins in the Cook Islands Dollar currency for collector's purposes.
Collector coins are dedicated to historical or general popular culture themes not related to the country itself. Many of them are in standard bullion sizes, including the large five ounces of silver format - such as this coin.
This coin is part of The 7 Summits collection. The seven summits are the highest mountains on each of the seven continents and enthralling subjects of one of CIT Coin Invest’s series, which displays the peaks in topographic detail from an unusual bird’s eye perspective in solid 5 ounces of fine silver. The coins are in Ultra high Relief (UHR).
The Mint says about the coin:
Our adventurous trip through the continents continues! This year we are heading for the arduous Carstensz Pyramid in Papua, Indonesia. Over the steep north face we ascend Oceania’s highest summit, which towers 4,884 meters above sea level. The Carstensz Pyramid is named after the Dutch seafarer and explorer Jan Carstensz. In Indonesia, the mountain is called Puncak Jaya by the indigenous people, which means victory peak.
The fifth edition of the series, created with our enhanced smartminting ultra high relief technology, features a vastly higher relief and is even more stunning than its predecessors. The refined partial colouring intensifies the detailed representation of the mountain. This splendid coin in solid 5 ounces of fine silver is not only worthwhile for passionate mountaineers, but also for you - the explorers, adventurers and nature lovers! |
