Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
The brave
and prudent conduct of the insurrection by the heroic family of the
Maccabees and the internal dissension in the Syrian empire did more
for them than the letters of their powerful allies; during the strife
between the Syrian kings Trypho and Demetrius Nicator autonomy and
exemption from tribute were formally accorded to the Jews (612);
and soon afterwards the head of the Maccabaean house, Simon son of
Mattathias, was even formally acknowledged by the nation as well as by
the Syrian great-king as high priest and prince of Israel (615).(39)
39. From him proceed the coins with the inscription "Shekel
Israel," and the date of the "holy Jerusalem," or the "deliverance
of Sion." The similar coins with the name of Simon, the prince
(Nessi) of Israel, belong not to him, but to Bar-Cochba the leader
of the insurgents in the time of Hadrian.
