| Obverse description | Central field occupied by a Carolingian-style interlaced monogram of Pope Eugene II, composed of angular and curved letter-strokes, enclosed within a beaded inner circle. The surrounding legend, separated from the monogram by the beaded border, runs clockwise in capitalised Latin characters. The striking is characteristic of early medieval hammered coinage, with slightly irregular flan and variable relief. |

| Additional information |
This joint issue reflects the Constitutio Romana of 824, by which Louis the Pious reasserted Carolingian authority over the papacy following a period of factional violence in Rome that had forced Eugene II to seek Frankish protection. The arrangement required papal elections to be confirmed by the emperor before consecration — a condition that would define, and eventually poison, the relationship between Rome and the northern crown for centuries.
Bipartite coinages naming both pope and emperor are exceptionally rare for this period. Eugene II's pontificate lasted only until 827, making the window for this issue narrow.
