Reverse description	The reverse features a finely engraved bust of the 9th-century Islamic mathematician Muhammad ibn Musa Al-Khwarezmi facing left, wearing a turban and draped robe, rendered in high relief against an elaborate geometric Islamic lattice pattern that fills the entire field. To the right of the portrait, a flowchart diagram with rectangular and diamond-shaped decision nodes symbolises the algorithmic concepts pioneered by Al-Khwarezmi. The legend HAREZMI arcs along the upper border within a recessed cartouche, and AL-KHWARIZMI appears in a corresponding cartouche along the lower border, both in raised Latin lettering. The overall design is framed by a plain raised rim.
