The world's first coins in the series "Stanislaw Lem, Master of Science Fiction". The combination of valuable bullion and the global science-fiction phenomenon is a recipe for a successful investment.     The coin was struck from 2 ounces of pure silver in a limited mintage of only 800 pieces worldwide! This factor makes it an excellent collector's coin. The reverse of the coin features a profile of Stanisław Lem according to a photograph from the 1960s, when he celebrated his greatest triumphs and when his most important novels and collections of short stories were written. In the foreground, a model of the rocket that was in his study can be seen. Stanisław Lem was a futurologist, which is why the coin was refined using unique, modern techniques: the background of the reverse is decorated with a metallic colourful print, while the rocket is selectively plated with gold. What is more - the coin glows in the dark! Selected parts of the image have been covered with fluorescent printing. The obverse shows a fragment of a character from Daniel Mroz's 1972 drawing for Stanisław Lem's 'Cyberiad'. The coin is packaged in an elegant wooden box (natural wood, boxes may differ in appearance) with a certificate attesting to its authenticity.
