I'm not entirely confident (the dates involved confuse me), but I
think this should qualify...

Seleucid Empire, AE unit (AE18)
Antiochos VII Euergetes (Sidetes), probably in opposition to Diodotus Tryphon
Dated 174 SE (ΔΟΡ) = 139/8 BC
Numista 140412, other references at link
Here's the chronology as I understand it from the Wikipedia description:
- July 138 BC: Demetrios II exiled by Tryphon, who enjoys sole rule for a few weeks
- early August 138 BC: Antiochus VII declares himself the legitimate heir of Demetrios II, gets immediate support from many parts of the empire
- late August (or early September?) 138 BC: Antiochus VII conquers the capital (Antioch), Tryphon retreats to Dor
- late 138 BC, date unclear: Tryphon dies in Apamea?
The year 174 SE ended on October 5, 138 BC, so this coin was issued at least that early, and it seems likely that Tryphon was, at least, still alive.
However, the rest of the chronology seems to have been heavily compressed (possibly by confusion between different varieties of the Seleucid era), so I'm not actually sure what happened when. There's
way too much reported to have happened in that one August; could they even communicate that fast at the time?
Quote:
In the one hundred and seventy-fourth year Antiochus set out and invaded the land of his ancestors. All the troops rallied to him, so that there were only a few with Trypho. Antiochus pursued him, and Trypho came in his flight to Dor, which is by the sea; for he knew that troubles had converged on him, and his troops had deserted him.

Note that the Jews' "one hundred and seventy-fourth year" is 138/7 BC, not 139/8 BC. They're not saying it happened before October: they're saying it happened after April.
