| Obverse description | The obverse features a stylised excerpt from the periodic table of elements occupying the entire field, rendered in relief with individual element cells displaying atomic numbers, chemical symbols, and full element names across four rows. The Guinean coat of arms is inset within the cell for element 28 (Nickel) at upper centre, framed by the legend REPUBLIQUE DE GUINEE above and the date 2026 below within the same cell. The cell for Gold (Au, 79) and Osmium (Os, 76) are prominently highlighted, referencing the coin's bimetallic alloy composition, with the word GOLD inscribed in a decorative cartouche replacing element 77 (Iridium). The denomination 2 000 FRANCS GUINEENS and the fineness inscription 1/6 OZ. 999 AU appear within the obverse field. |

| Additional information |
Guinea's use of osmium in a gold alloy here is genuinely unusual — osmium is the densest naturally occurring element and notoriously difficult to work, making its inclusion in a struck coin composition a modern technical curiosity rather than a historical tradition. The practical effect on die wear and striking pressure at this scale is not yet well-documented in the numismatic literature, simply because so few mints have attempted it.
