2022 Austria 25€ Extraterrestrial Life Niobium Silver Coin
Pioneers of the use of niobium in collector coinage, the Austrian Mint's latest effort sees them use this rare metal to discuss the search for extra-terrestrial life! In particular, this purple coloured collectable honours the Webb telescope that was launched recently to examine far off galaxies! Whilst not outwardly designed to search for E.T., the telescope's infrared abilities will no doubt shine a light on whomever - or whatever - is out there!
Struck on an outer core of 90% pure silver, combined with a central disc of niobium - a metal which changes colours dramatically, depending on the temperature which it is heated - this is a beautiful coin. The purple and green shades are striking.
Tremendously popular every year since first release in 2003, the 2022 Niobium coin is out of this world...
