Diodotos I, who was a high official, attempted to gradually secede from the Seleukids when he first issued coins bearing a the name of Antiochos, and later on struck in his own name. Jakobsson ("Antiochus Nicator, the Third King of Bactria?," NC 2010, pp. 17-33) refutes this model and reassigns these "transitional" issues from Diodotos to a new King Antiochos in Baktria. His argument rests on three main points: the existence of a commemorative tetradrachm of Agathokles that names an Antiochos Nikator; a new arrangement of the control marks and links between the coinage of Diodotos II, "Antiochos," and Euthydemos; and the generally overcomplicated nature of the earlier models of Holt and Kritt. According to this new theory Diodotos I broke from the Seleukids not gradually but swiftly and struck coinage in his own name. He was succeeded by Diodotos II, then Antiochos Nikator, who both continued with the same dynastic type of Zeus Bremetes.
