King Faisal's iron riyal, may God have mercy on him, and Fahd's paper riyal, may God have mercy on him. The paper riyal is new, I expect it has not been used due to its cleanliness. The iron riyal is equivalent to 100 halalas. For lovers of rarities, history, and everything old. The price is by offer. There is a video by Saleh Al-Fawzan about the matter below.
