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 commemorative, collector and bullion coins under the authority of Niue. These coins are dedicated to historical or general popular culture themes not related to Niue itself. Some of them are in the mini-coin format of half gram of gold (abbreviated as 0.5 g Au, where "Au" comes from the Latin word for gold, Aurum).
This coin is part of the "Czech Lion" series of gold and silver coins, minted since 2017 with a new design every year. The weight of this gold mini coin by the Czech Mint is one half of a gram. It was only issued as part of a four-coin set.
The Mint says about it:
The author of the original 2019 composition was medal maker Jaroslav Bejvl, who left us forever at the age of 75, so he did not manage to finish his masterpiece; Asamat Baltaev completed this masterpiece. The reverse side of the coin is dominated by a non-traditionally realistic two-tailed lion which guards the St Wenceslas crown, along with a flaming eagle on the shield. |
