Interesting. Haven’t seen one of those before, but it’s loosely copied from a coin of Trajan. There are some blunders in the legend, which is supposed to read:
IMP CAES NERVAE TRAIANO AVG GER DAC P M TR P COS V P P, short for “Imperator, Caesar, Nervae Traiano Augustus, Germanicus, Dacicus, Pontifex Maximus, Tribunicia Potestate, Consul Quintum, Pater Patriae” translated as “Supreme commander (Imperator), Caesar, of Nerva Trajan, emperor (Augustus), conqueror of the Germans, conqueror of the Dacians, high priest, holder of tribunician power, consul for the fifth time, father of the nation”.
The reverse has a mourning Dacia seated on pile of arms before a tropaeum (trophy) and the legend S P Q R OPTIMO PRINCIPI, short for “Senatus Populusque Romanus Optimo Principi” translated as “The senate and the Roman people to the best of princes” with SC in the exergue for “Senatus Consulto” (indicating that it was an official coin, authorised by the Roman Senate - the original, that is). Similar to this dupondius, struck (in bronze) between AD 108-110:
