50 Baisa - Qaboos

This issue falls within the long coinage program of Sultan Qaboos bin Said, who took power in a 1970 palace coup that deposed his own father, Said bin Taimur. The elder sultan had kept Oman in deliberate isolation — no schools, no hospitals, no modern roads — and the coinage reform that followed the coup was part of a sweeping modernization that introduced the rial Saidi and, shortly after, the rial Omani monetary system. The Schön#54.2 designation distinguishes it from the earlier 54.1 subtype, reflecting a detail revision in the series.
