The 1/5 20 Mauritanian ouguiya set is made up of the six new ouguiya coins, first introduced in 2017. The coins are made of different metals and shapes. The bigger the value of the coin the bigger the size. The obverse side of the coins all depict the same image: the national seal of Mauritania at the center, with the Central Bank inscription and year of issue above and the face value below in Arabic. The reverse side of the coins feature different animals and items at the center, surrounded by an inscription of the year of issue and face value of the coin in Arabic.
