20 Rials - Mohammad Rezā Pahlavī 7th Asian Games

Iran hosted the 7th Asian Games in Tehran in October 1974, a massive organizational undertaking that the Shah used deliberately to project modernizing ambition onto the international stage. The games drew over 2,000 athletes from 25 nations — the largest Asian Games to that point. This coin was issued as a commemorative tied directly to that event, part of a broader pattern of Pahlavi-era commemoratives minted through the Tehran and foreign facilities during the 1970s boom in state coinage.

It would be the last time Iran hosted a major international sporting event before the 1979 Revolution permanently altered the country's relationship with such ambitions.
