"50th anniversary of the moon landing" silver coin

The first such curved key embossing

"That's one small step for a man, one giant leap for mankind." On July 21, 1969, Neil Armstrong became the first man to walk on the moon.
To mark the 50th anniversary of this historic event, the Austrian Mint issued a truly exceptional silver collector's coin.

Not only is our Earth, which stands in the background in the firmament, highlighted in color, but it also glows like the stars in the dark. The unusual feature of this silver coin is the curved bowl minting.
One side of the coin curves outwards, the other inwards. While the convex side shows the barren, crater-strewn lunar surface with the marked landing site of the Apollo 11 mission, the "inner" concave side shows the scene on the moon with the lunar module, an astronaut and the Earth in the sky. Earth in the sky.
