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:
With a height of 5,642 m Mount Elbrus is the most elevated summit in the Caucasus mountain range and the highest mountain in Russia. But is the cone-shaped rock massif with its double peak also the highest in Europe? This depends on the definition of the inner Eurasian border, it could undoubtedly be Mont Blanc as well. Nevertheless, we have decided to add Elbrus to our series as the highest mountain in Eurasia. This 6th edition of the Seven Summits series impresses with our enhanced smartminting technology and a refined colouring that shows the heavily glaciated, dormant volcano in all its beauty.
The detailed topographic relief, in 5 oz silver, is a reminder of how ambitious the first ascent must have been in 1874. The ultra-high relief extends well above the surface of the coin. This spectacularly depicted force of nature is worthy of a place alongside the other editions of this stunning series. |
