CARo _ LVS (inscribed in two lines with one globule between the letter A and the letter V).
M - A _ SL - S (inscribed in two lines, a large cross in the middle. A letter at each corner of the cross: the letter M at the top left, the letter A at the right, the letter S inverted at the bottom left and the letter S reversed at the right. A tilde above the cross).
Photo of the copy preserved at the Bibliothèque Nationale de France (public domain), link to the page of their website showing the photo of the coin: https://gallica.bnf.fr/ark:/12148/btv1b10413652b.r=charlemagne%20denier?rk=321890;0.
One copy preserved at the Münzkabinett der Staatlichen Museen of Berlin, link to the page of their website showing the photo of the coin: http://www.smb-digital.de/eMuseumPlus?service=ExternalInterface&module=collection&objectId=2448403&viewType=detailView. This coin seems to have the same dies and the same centering as the illustration of Patrick Nouchy in his book "Les Rois Carolingiens de Francie Occidentale" de Pépin Le Bref à Louis V, page 55. But the blank of the copy of Berlin is broken, which is not the case in the illustration showing a completely round blank. On the other hand, it is certain that this currency has the same coins as the copy of Bibliothèque Nationale de France.
