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 bullion sizes based on the troy ounce, but some are "metric", like twenty grams (20g) of silver.
This coin is part of a heart-shaped series issued (almost) annually, with a new design every year.
The mint says about it:
An ode to the butterflies in your stomach, to the new, the familiar, the unpredictable, the exciting. The unyielding love for your partner, your child, your friend, your mother... No matter for whom, love rises above all.
The 13th edition of the silver heart series attracts with a magnificent crystal and delicate colours. |
