Depicts a value within the crowned wreath, an inscription above "Mohammad Shah Shahanshah of Iran" in Persian. Date below in Monarchical Calendar System (MS) or in Solar Hejira (SH).

Mohammad Reza Shah adopted the title Shahanshah ("King of Kings") on October 26, 1967.

During his reign, Iran commemorated 2,500 years of continuous Persian monarchy, tracing back to the founding of the Achaemenid Empire by Cyrus the Great. In conjunction with these celebrations, Mohammad Reza altered the Iranian calendar’s benchmark, shifting it from the Solar Hejira (SH) to the establishment of the First Persian Empire, dating from Cyrus the Great's coronation. This Monarchical Calendar System (MS) was officially introduced in 1976 but was abandoned in 1978. The Solar Hejira, which had been in use since 1925, was reinstated following the MS's repeal.

Depicts an Emblem of the Imperial State of Iran (radiant lion holding sword, 1932-1980) within a crowned wreath. Value in Persian below.

The Lion and Sun motif is one of the better-known emblems of Iran. The motif has many historical meanings. First, it was an astrological and zodiacal symbol. Under Safvis and first Qajar kings, it received a specifically Shi'ite interpretation. In Safavid era the lion and sun stood for two pillars of the society, state and religion. It became a national emblem during the Qajar era.

At the top of the coat of arms was the Pahlavi crown, created for the Coronation of Reza Shah in 1926, and the collar of the Order of Pahlavi was under the shield.
