| Obverse description | Central field depicts a highly stylized, faceted three-dimensional representation of two protons at the moment of high-energy collision, rendered in a geodesic polygonal style with radiating energy spikes emanating from the point of impact. Concentric circular rings in the field evoke particle detector cross-sections or rippling energy waves, while angular bracket-like motifs at the cardinal points suggest detector instrumentation. A diagonal band in the lower right field provides contrasting texture. The legend UNIVERSE OF PARTICLES curves along the lower field, with the acronym CERN prominently incused at the bottom. |
