Sear identifies them as 'reduced' double sestertii. The noble attempt of Postumus to restore the old currency was doomed by one inescapable fact. Bad money chases out good. Postumus could issue 'good' silver but it surely disappeared as soon as it was circulated. No one with half a brain would spend the 'real one' and keep the Gallienus antoniniani. Same with the double Sestertii. They would not have lasted long with all the 'crap' coinage in circulation. Nice coin by the way !
