| Reverse description | The silhouette of the Shanghai skyline, featuring recognisable landmarks including the Oriental Pearl Tower and the Shanghai World Financial Center, rises dramatically from a wavy baseline rendered in polished silver relief against a heavily textured, black ruthenium-plated field. The upper portion of the field is dominated by an elaborate guilloché-style spirograph pattern in ruthenium, creating a striking contrast with the bright skyline. The legend 'NOBLE BAR' appears in bold uppercase letters along the upper edge, and a small circular 'RU' hallmark is present in the lower field, denoting the ruthenium finish. |

Cameroon's high-denomination collector issues of this type are produced under licensing arrangements typical of the African novelty bullion market, where the issuing state lends its legal tender authority to a European private mint — in this case almost certainly B.H. Mayer's Kunstprägeanstalt in Munich or a comparable contractor. The coins have no meaningful circulation history and are manufactured entirely for the international collector market.
Ruthenium, one of the rarest platinum-group metals, was not used in numismatic finishing until the 2010s. Its appeal is purely aesthetic — the black finish resists tarnish better than traditional oxidized silver treatments.
