[1] There were about 300 to 400 coins in the hoard when local antiquary Anatole de Charmasse saw them in 1873, identified 55 types, took down legends and drew sketches.
Eleven of the coins came from the mint of Chalon-sur-Saône and the latest datable Merovingian issue was struck in the name of Chlothar II at Marseille between 612 and 629.
If dated to shortly before 693, when a new coinage was introduced by the Caliph ʿAbd al-Malik ibn Marwān, it is inconsistent with the rest of the Buis hoard.
[1] Clive Foss suggests that the dīnār, which bears no Christian symbol, is among the issues of the Caliph Muʿāwiya I that were rejected as tribute by the Emperor Constans II in 659.
[2] The representation of mints along the Rhône, Saône and Meuse rivers reflects Buis's place along the trade route connecting the Mediterranean and the Rhine through eastern Francia.
