Denarius Rubria: Lucius Rubrius Dossenus, DOS / L•RVBRI

Lucius Rubrius Dossenus served as moneyer in 87 BC, the same year Sulla marched on Rome for the first time and Cinna and Marius seized the city in a bloody purge of the optimates. The political chaos of that year makes attribution of any mint activity difficult — it remains debated whether some issues of this period were struck under the authority of the senatorial government before its collapse or during the brief interregnum that followed.

The control mark DOS beneath the main type is among the more consistently documented on this issue, cross-referenced across the BMC and Crawford die studies without significant variation.
