Karl der Kahle, 843-877. Obol, Melle. 0,81 g. M./G. 1061; Depeyrot 625.

Die ausschließliche Zuweisung der Monogramm-Obole an Karl den Kahlen (843-877) ist vor einiger Zeit von S. Coupland in Frage gestellt worden, der auch eine Prägung unter Karl dem Großen (768-814) für möglich hält: "Several of Charlemagne's mints also struck monogram oboles, or half-deniers. In the past, these have all been attributed to Charles the Bald, in part due to the misconception that minting of oboles began under Louis the Pious. [...] That they are coins of Charlemagne and not just Charles the Bald is clear from their manufacture at, for instance, Dorestad, where Charles the Bald never minted, since he never ruled there. The oboles listed by Morrison and Grunthal under Charles the Bald's name should consequently be restored to Charlemagne [...], although as we have seen, some of these were minted under both rulers."
