5 Rials

The fifth series of Omani rials, of which this note is part, coincided with the steady expansion of Oman's non-oil revenue diversification program under Sultan Qaboos — though that policy shift is invisible on the note itself. What matters more to collectors is that Thomas De La Rue produced these to a high technical standard, and the 5 Rial denomination in this series has proven more common in circulated than uncirculated grade, suggesting it bore genuine transactional load rather than sitting in savings.

The watermark remains the primary security feature — modest by the standards De La Rue was already deploying on other contracts by the mid-1990s.
