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).
This coin was issued as part of a Royal Mint twelve-coin set featuring Endangered Wildlife, and is dedicated to the Deer.
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, the fallow deer, and the chital; and the Capreolinae, including the reindeer (caribou), the roe deer, the mule deer, and the moose. Female reindeer, and male deer of all species except the Chinese water deer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla).
The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae.
Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry. Their economic importance includes the use of their meat as venison, their skins as soft, strong buckskin, and their antlers as handles for knives. Deer hunting has been a popular activity since at least the Middle Ages and remains a resource for many families today.
