| Descripción del anverso |
Blank trial obverse die, fully uniface, with a centrally punched circular hole through the planchet. The field is entirely plain with no devices, legends, or inscriptions, consistent with its status as a reverse trial piece intended to test the proposed reverse design in isolation. |

| Descripción del reverso |
A large six-pointed Star of David (hexagram) formed by two interlaced equilateral triangles dominates the central field, with the circular hole at its center. The legend BRITISH WEST AFRICA arcs around the upper periphery, and the date 1920 appears in the lower field flanked by two raised dots, all set within a fine beaded border. |

Trial pieces for the British West Africa series were produced at the King's Norton Metal Company in Birmingham, which held the contract for these colonial issues in the early 1920s. This reverse trial exists to test die alignment, metal flow, and surface quality before full production runs were authorized — making it a working document in metal rather than a collectible in the conventional sense. King's Norton was absorbed into ICI in 1962, and much of its trial piece documentation was lost.
