Marius (Marcus Aurelius Marius) 269 Gallo-Roman Empire
Spring 269 Postumus assassinated after he refused to allow his troops to pillage Mainz (conquered on Laelianus March-April/May 269)
May 269 Marius proclaimed emperor by his troops
He too fell victim to the violent soldiery
In the 'Historia Augusta' is written that he was killed with a sword of his own manufacture (seems rather fanciful)

Mints:
Cologne (bulk)
Mainz or Trier, mint opened by Laelianus (smaller issue)
