Niue, a sovereign state in free association with New Zealand, uses two official legal tender currencies. The New Zealand Dollar is the circulation currency for daily transactions, while the government also authorises legal tender coins in the Niue Dollar currency for collector's purposes.
A number of mints issue a large variety of coins under the authority of Niue. Most of these are commemorative and collector issues dedicated to historical or general popular culture themes not related to Niue itself. Many of them are in standard bullion sizes - including the very large ten ounces of silver format (abbreviated as 10 oz Ag, where "Ag" comes from the Latin word for silver, Argentum).
This coin is part of the Slovakia Eagle ("Orol") range of premium bullion coins issued by the Czech Mint.
The Mint says about it:
The Slovaks waited patiently for the opportunity for self-determination for a long time - like a bird of prey circling in the sky over the majestic Tatra Mountains and looking out for its prey. It is no wonder that Slovak poets and revivalists of the 19th century took the eagle as a soul mate and that Ľudovít Štúr himself named the cultural supplement of the Slovak national newspaper "Orol tatránski" (The Tatra Eagle). Despite the efforts of their earlier rulers, the Slovaks retained their culture, language and character until they finally managed to gain independence. The symbol of all they have achieved has again been the eagle, which has represented power, victory, freedom and grandeur, but also a restoration and a new life. The predator, which is a representative of the Christian heavenly kingdom, also refers to the Slovak religious tradition.
