Ringed bimetal coins are used in circulation in Saudi Arabia. Saudi Arabia’s Crown Prince and First Deputy Prime Minister Mohammad bin Salman bin Abdulaziz Al Saud (better known as MBS) has been in the news recently for flexing his financial muscle in advance of inheriting the thrown from his father, King Salman, who is still alive. MBS has recently had some members of the royal family arrested, intervened in war-torn Yemen, and proposed controversial economic, social, and religious changes into the future through a plan called Saudi 2030. MBS’ footprint can already be seen on Saudi Arabia’s currency as well. At his instruction, the kingdom was preparing to introduce 1- and 2-riyal coins in early December, while phasing out the existing 1-riyal bank note. Saudi Arabia currently uses coins in denominations of 1, 10, 25, and 50 halala. (100 halala equals one riyal.) The Saudi Arabian Monetary Agency currently issues bank notes in denominations of 1, 5, 10, 50, 100, and 500 riyals.
