Depicts a national seal of the Comoros above denomination, date below, and Emission Institute in the bottom.

The date is surrounded by the Paris Mint mark (Cornucopia, left) and the engraver general's privy mark (dolphin, Émile Rousseau, 1975, right).

The national seal of the Comoros features a crescent, taken from the national flag, at its center, containing the four stars that represent the four islands of the Comoros. The star and crescent symbolize Islam, the dominant religion of the nation. Above the crescent is a sun with extended rays. Encircling the central design is the name of the nation (Union of the Comoros) in both French and Arabic. The border consists of two olive branches, with the national motto in French at the bottom.

On December 31, 1974, the Comoros Emission Institute was established with its head office in Moroni and its administrative headquarters in Paris. On January 2, 1975, an agreement was signed between the Comoros' Minister of Economy and Finance and the French Secretary of State for Overseas Departments and Territories. This agreement outlined the transfer of authority for issuing banknotes and coins to the Comoros Emission Institute and provided for the opening of an operations account with the French treasury, detailing its operating conditions.
