I'm sure this Philip Philadelphus tetradrachm of Antioch was minted later, under some Roman governor of Syria. But which one? The date is off-flan and I cannot recognize the monogram, a K ?, in the lower left field. Or is it an imitation, or a fake? Philip Philadelphus, tetradrachm, Antioch. AR 23-27 mm, 12.99 g, 12 h.
I wish I could help; you've come to the ID rescue for me before. However, the Philip series isn't my forte. As a coincidence, I just bought one. It's rather hideous in person but has the original hoard patina, I think.
It's a modern replica, details soapy and underweight. The obverse is SC 2488 paired with a non existent reverse.
I thought it also looked strange, but I don't usually pipe up. It's too embarrassing to be wrong. I've noticed that some of those fakes have that unusual reddish encrustation in the fields. Here's my recent, ugly example (hopefully authentic). It's actually quite unattractive in hand (picture looks better) but has most of the original hoard patina, which adds some interest. Attribution: SC 2488.2 Antioch Date: 69-57 BC Obverse: Diademed head right Reverse: ΒΑΣΙΛΕΩΣ / ΦΙΛΙΠΠΟV / ΕΠΙΦΑΝΟVΣ / ΦΙΛΑΔΕΛΦΟV, Zeus Nikephoros seated left; A in inner left field; H in exergue Size: 24.90mm Weight: 15.15 grams Ex CNG Electronic Auction 303 (29 May 2013), lot 73 with tag.
Someone asked me to look at this discussion, so I'm replying. The coin looks just fine. Very worn, photo out of focus,probably slightly crystalized and the encrustations look genuine. Concerning the comments that it's a non-existent reverse..... nonsense. It's SC 2463.2g. these also come with a retrograde K. Here's another example from the same obverse die in better condition. barry murphy
