The majestic sperm whale, a gentle giant and tourist attraction around Kaikura on New Zealand’s east coast of the South Island is celebrated in this latest coin issue. Minted from 0.999 silver. Limited worldwide mintage of 1,500. Unique blue enamel finish which mimics the ocean over the image of a sperm whale and her calf. Set in an acrylic block that provides a wider scenic image of the Kaikura ranges, and housed in a premium leatherette case. Sperm whales are quite long lived, with females taking about 30 years to reach physical maturity, and larger males up to 50 years. Females won’t start breeding until they are around 9 years of age, and they then only give birth to one calf every five years. Females calves usually stay with their mum’s pod for life, while males will split off after around four years, at which point it will often form a pod with other young males until they reach sexual maturity at around 18 years of age. In this detailed coin design, a mother and her calf can be seen diving in the deep oceans off the coast of Kaikura. In the background is the majestic Mt Fyffe and the seaward Kaikura ranges. This 1oz silver proof coin has had enamel syringed onto its surface to create the glossy coating of water. This coin is housed within an acrylic block that is a continuation of the scene depicted on the coin itself. Packed snugly into a baby blue, leatherette case, this collectable will add a dash of colour and intrigue to your collection. One New Zealand dollar.
