1 Rial Frankincense Tree

Oman's frankincense trade predates its coinage by millennia — Dhofari boswellia trees supplied resin to ancient Egypt, Rome, and the incense routes of southern Arabia long before any central bank existed to commemorate them. The species native to Dhofar, Boswellia sacra, remains commercially harvested today, one of the few such traditions in the Arabian Peninsula that survived the oil economy largely intact.
