Roman Bronze Ae14?

Thanks, echizento. Now that you mention it ... there could be an eagle there, although all of the examples I saw depicted the eagle more to the center of the coin and with other standards on either side. Maybe this one was an off-center strike and is worn so badly that the other standards have been lost?

I need to check on those white specks - may be time to clean the glass on the scanner! I can always rescan, resize, retweak, etc., if anyone needs a better image to view. If this one is real, it would be my oldest Roman coin, so I have high hopes.

I didn't post when I saw this thread earlier, because I didn't know what it was. I still don't.

At the time of Marc Antony, Rome wasn't issuing much on the way of bronze coins, as you can tell from a glance at the Wldwinds page. On Wildwinds, the colour strip down the left side indicates the composition of the coins; for Antony, it's mostly grey (silver), very little brown (copper). Most of the Antonine "galley coins" are silver denarii. They're also usually very wordy. This "light as" is the closest Antonine bronze coin to yours, and it's not a very good match. These early Roman depictions of galleys tended to show them under full sail.

There was a much later issue of coins with galleys from the rebel pirate empires of Britain, from Postumus to Allectus, which showed the sails and mast much less prominently, like on yours. See here for examples, like this one. Your coin may well be a "barbarous imitation" of one of these, with the thing on the obverse a somewhat degenerate radiate portrait. I know the earlier large Postumus bronzes have barbarous copies; see here on FORVM.

The other option I can think of is a small Greek bronze, with the obverse being the remnants of a turreted portrait of Tyche, or maybe the Seleucid king. The cities of the Phoenician coast seem to have used such designs; Example from Tyre, example from Sidon. I think I can see some lettering that looks Greek, above your ship, but I could just be imagining it.
