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, but the silver Fifty Dollars listed below are not; their weight is more than a half ounce but less than one ounce, and also less than that of a British Crown, even though the diameter is the same as the latter (hence, the coins are thinner). |
