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 or for investment.
Many of these are in standard bullion sizes, including one ounce of silver. The coins listed below are are priced around their intrinsic value; for collector pieces in the same format but issued at a high premium, see of the list of "Non-Circulating Legal Tender" (NCLT) silver ounce coins. |
