There was an initial emergency issuance of 25- and 50-centime and 1-franc notes on 28 April 1920, followed by a second issued of 25-centime and 1-franc notes with different color schemes. The violet 25-centime notes are available with and without embossing, which was used to validate the notes, but the process was soon discontinued as a cost-cutting measure. The embossed notes have a crowned shield with diamond pattern at center, encircled by the text Principauté de Monaco, and are available with circles of two different diameters.[4][5]
