Hello Loukianos, thank you for your reply. I studied the net a little and think you are right it's from one of those Phoenician cities (
Sidon, Arados, Tyros). I have the coin in hand now and it looks slightly different than I thought from the picture. So now I MS-PAINTed again:
Red: Water with ship r. and oarsmen
Blue: Three letters
Green: Another letter or the mast of the ship?
Yellow: The dotted outline of the
incuse square.
What I didn't find anywhere is the letters in the
field. Can anybody read them? They should
help to pin down the city.
Thanks in advance,
Rupert
