National Coat of Arms - 15 Fils

This definitive postage stamp was issued in 1965 by the Federation of South Arabia, a British protectorate established in the southern portion of the Arabian Peninsula centered around the strategic port city of Aden. Released as part of a foundational definitive series to overhaul the territory's postal infrastructure, this 10-fils denomination served standard domestic civil mail rates. By featuring newly consolidated state heraldry, the issue sought to project a cohesive administrative identity across the various sultanates, emirates, and sheikhdoms unified under the federation.

The central design showcases the official Coat of Arms of the Federation of South Arabia. The insignia features a central traditional dagger (jambiya or janbiya) inside a crescent-shaped shield, topped by a prominent five-pointed star. Flanking the central emblem are twin draped flags of the federation, crossing below the shield base. The elegant slate-blue design is framed by the English inscription "FEDERATION OF SOUTH ARABIA" running vertically and along the baseline, balanced by the Arabic name at the top, "Ittihad al-Janub al-Arabi" (اتحاد الجنوب العربي). Circulating widely on daily civil correspondence, this stamp functioned as an official visual signature of the region's unified administrative authority.
