1 Rial 39th National Day - Yellow-vented Bulbul

Oman's annual National Day coinage program, administered directly by the Central Bank, has produced commemorative silver issues nearly every year since the early 1970s — each tied to a specific theme chosen to reflect the sultanate's natural or cultural heritage. The Yellow-vented Bulbul, native to the Arabian Peninsula's coastal and cultivated zones, was selected for the 39th National Day falling on November 18, 2009, marking thirty-nine years since Sultan Qaboos bin Said deposed his father in the 1970 palace coup and initiated Oman's rapid modernization.
