The 5-franc coin is nicknamed "reali", referring to the Spanish real; the 2-franc coin is nicknamed "nusu", meaning "half", and the 1-franc coin "robo", meaning "quarter". The 1-, 2-, 5- and 10-franc coins are rarely used because of their low value. The 25- and 100-franc coins contain the phrase "Augmentons la production alimentaire" ("Let's increase food production"). The 5-franc coin contains the phrase "Conférence Mondiale sur les Pêches" ("World Conference on Fishing"). Both of these phrases are references to programs by the United Nations Food and Agriculture Organization. Comoros is one of 114 countries that have issued FAO coins.
