| Reverse description | The reverse features a vivid, color-treated depiction of a black hole accretion disk, rendered in deep tones of amber, gold, and violet against a dark cosmic field scattered with star symbols and luminous particles. At the centre, a convex dome of polished silver represents the black hole itself, within which a silhouette of a swan — referencing the Cygnus X-1 binary system — is subtly visible. The surrounding accretion disk glows with graduated hues, conveying the extreme energy and radiation of the astrophysical phenomenon. The legend SCHWARZES LOCH arcs along the upper border in raised Latin lettering against the dark field. |
