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 depicts the novel's main character, psychologist Kris Kelvin, who arrives from Earth at a research station floating above the cytoplasmic ocean that covers the planet Solaris. It is a scene from the finale of the novel , when Kelvin alone explores the surface of Solaris amidst the fantastic shapes created by the living ocean. 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 star 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, on the other hand, features an adaptation of Daniel Mroz's graphic design. The coin is packaged in an elegant wooden box (natural wood, boxes may differ in appearance) with a certificate attesting to its authenticity.
