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:
Mount Everest, Denali, now Aconcagua - the third of the seven summits features the highest mountain outside of the Himalayas. At 6,962 meters, Aconcagua might be one of the lesser known seven summits but it certainly is one of the most spectacular ones. The “Sentinel of Stone” is arguably the most elaborate coin in the series yet with an unbelievably detailed, high-rising, topographical smartminting relief and a selective colour application that clearly defines the different rock strata present in the Andes mountain range. The snow and ice capped summit is surrounded by hues of green and red that represent limestone, carbonates, cinder deposits and rock of volcanic origin.
Aconcagua was first climbed in 1897 by Matthias Zurbriggen. The hardships of this adventure can be vividly imagined when looking at the miniature mountain on this numismatic artwork. |
