| Descrizione del dritto |
Central brass field features a stylized geometric depiction of a mineral crystal, rendered in bold relief with faceted planes suggesting a dodecahedral or pyritohedral form. The design is abstract yet mineralogically evocative, occupying the full center of the coin. The surrounding copper-nickel ring bears the circular legend 'GRUP MINERALOGIC CATALA' along the upper arc and the commemorative dates '1975 · 2025' along the lower arc, separated by decorative stops. The overall composition celebrates the fiftieth anniversary of the Catalan Mineralogical Group. |

| Descrizione del rovescio |
Central brass field displays a large numeral '2' overlaid on a stylized relief map of Europe, closely following the standard design language of the euro coinage series. The copper-nickel outer ring is inscribed with the multilingual legend 'ESSAI · PRUEBA · TRIAL · PROVA' repeated around the full circumference, each word separated by a raised dot, indicating the piece's status as a trial or essay strike in four languages (French, Spanish, English, and Catalan/Italian). |

The Grup Mineralògic Català is a private association, not a sovereign state or monetary authority, which means this piece has no legal tender status anywhere. It is a fantasy issue — struck to the dimensional and compositional specifications of genuine euro coinage but carrying no authorization from the European Central Bank or any national mint within the Eurozone. Pieces like this occupy an awkward legal grey zone in several EU member states, where replicating euro specifications without authorization can conflict with anti-counterfeiting statutes regardless of intent.
