| 正面描述 | Bimetallic coin with a nickel-plated steel centre set within a brass-plated steel ring. The centre features the national emblem of Mauritania — a crescent and star flanked by two palm branches — above which the date is split as '20' to the left and '09' to the right of the device. The large denomination numeral '20' appears prominently in the lower centre field, with the legend 'OUGUIYA' immediately below it. The encircling brass ring bears the issuer's legend 'BANQUE CENTRALE DE MAURITANIE' around the full circumference in raised Latin letters. |

Mauritania's ouguiya is one of only two world currencies not based on a decimal system — one ouguiya divides into five khoums, a structure rooted in traditional West African exchange ratios rather than colonial monetary convention. France had issued the CFA franc across the region, but Mauritania abandoned it in 1973 upon establishing the Banque Centrale de Mauritanie and introducing its own currency as a deliberate assertion of post-independence economic policy.
The bimetallic format arrived with the 2009 series, replacing an earlier monometallic issue of the same denomination.
