| Obverse description | The central aluminium bronze disc bears the national arms of Oman — two crossed khanjar daggers over two crossed swords — centrally placed above the Arabic denomination '١٠٠ بيسة' (100 Baisa). The legend 'قابوس بن سعيد' (Qabus bin Sa'id) arcs along the upper portion of the copper-nickel outer ring, while 'سلطان عمان' (Sultan of Oman) curves along the lower ring. The Hijri date '١٤١١هـ' appears to the right and the Gregorian date '١٩٩١م' to the left within the ring, with 'البنك المركزي العماني' (Central Bank of Oman) inscribed across the lower centre of the inner disc. |

| Additional information |
Oman introduced bimetallic coinage in 1991 as part of a broader modernization of its circulating series under the Central Bank, which had only been formally established in 1974 — itself a product of Sultan Qaboos's sweeping administrative reforms following the 1970 palace coup that deposed his father Said bin Taimur. The aluminium bronze and copper-nickel combination was chosen for its resistance to the Gulf's corrosive humid climate and to deter counterfeiting of the highest-value circulating coin in the series.
The 100 Baisa denomination represented one-tenth of a Rial Omani, a currency that had replaced the Gulf Rupee only in 1972.
