Note: Rostovtzeff suggested this type might be connected to the games (certamen quinquennale) of AD 60, since he thought that was
the best context for understanding the title Invictus here (Römische Bleitesserae p. 74). The legend on side b Rostovtzeff
suggested should read Pedo (et) Paetus mag(istri). The specimen of this type, once in Baron Recupero's collection, was already
missing in Rostovtzeff's time.
