Tokelau, known previously as the Tokelau Islands, is a dependent territory of New Zealand in the southern Pacific Ocean. It uses the New Zealand Dollar as circulation currency, but has been issuing a variety of non-circulating coins since 1978. These are denominated in dollars or "Tala" (the local word for dollar) and cents.
The country has also authorised some foreign mints to issue non circulating bullion coins under its jurisdiction, such as this 1 oz (one ounce) gold coin.
This is the fifth design in the Equilibrium series of bullion coins by the Pressburg Mint, and the second one issued in gold. The coins in the series have a new design every year and are about balance - equilibrium - between technology and humanity.
The Mint says about it:
The yin-yang is an especially important and popular representation of harmony, sprouting from the rich Asian tradition in philosophy. Humanity has already explored much of our planet Earth. Now, we are not only focusing outwards into space, but inwards into our consciousness as well. What is the relationship between our own selves and the great vastness beyond? |
