The seventh silver coin from the Milky Way collector's series is dedicated to Halley's Comet.

Comets, which are primarily composed of ice and dust, orbit the Sun in eccentric elliptical orbits. They regularly return to their parent star, as predicted by English astronomer Edmund Halley. The most famous comet, named in his honour, is the only one that appears at relatively short intervals and is visible to the naked eye. Moreover, it can be seen from Earth every 76 years. While its nucleus is 15 kilometres across, its tail of dust and gas stretches millions of kilometres away…

The reverse side of the coin was dedicated by the medal maker Asamat Baltaev, DiS., to a dynamic depiction of Halley's Comet in vivid colours, achieved through the use of colouring technology. No photographs or computer graphics were used as the motif - the author of the coin created an original watercolour painting. Stylized space objects - the Earth, the Moon and the stars - are visible in the embossed relief, and the composition is completed with the English inscription HALLEY'S COMET. The obverse side of the coin humorously presents crop circles and a flying saucer illuminating the national emblem of Niue. This, together with the year of issue 2023 and the nominal value of 1 DOLLAR (NZD), is a necessary attribute of the foreign issuer of the coin - a Pacific island that provides the Czech Mint with a licence to mint its own commemorative coins.

The coin dedicated to Halley's Comet can be placed in a collector's album full of interesting facts about our home galaxy and the space conquerors.
