Special uncirculated , niobium
Description of obverse and reverse
Obverse: The coin displays a three-quarter portrait of the famous mathematician and astronomer Galileo Galilei (1564-1642) and his telescope with which he observed the surface of the moon just four hundred years ago in 1609. In the background his drawing of the moon surface is reproduced, while the silver ring spans the development of the telescope from Newton’s telescope through the observatory in Kremsmünster (Upper Austria) to radio telescopes and those launched into space – a far cry from Galileo’s first views of the moon.
Reverse: The official side of the coin with the face value and legend "Republik Österreich" shows the dark side of the moon that Galileo could not observe. A satellite is shown orbiting the moon and surveying its surface. In the ring one sees the planet Earth partly covered by the moon and below a stylised Sun radiates the heavens.
