Using the following and knowing when the honors were given to an emperor, it is possible to figure out the date range when a coin might have been struck:
P M = Pontifex Maximus: High Priest or Chief Pontif
TR P = Tribunitia Potestas: The Tribunal Power for the first time
TR P II = Tribunitia Potestas: The Tribunal Power for the second time
COS I = Consul for the first time
COS II = Consul for the second time, etc.
PP = Pater Patriae Father of the Fatherland, or Father of our country
