Can you please confirm the size? Is it actually 21 mm? Also, are there letters behind the
bust?
If the size is right, and there are letters on the
obv, then it is not the coin I thought it was, which is
RPC I 4322, AE 16, 5.4 g, civic series of
Antioch,
Syria, AD 68-9, under
Galba and
Otho (year 117 of
Antioch). Laureate
head of
Zeus, r. Garlanded and lighted
altar; in
exergue (off
flan) ET ZIP.
Here's a photo of the coin I think it is, however it is not this coin
for certain if there is a
legend on the
obverse. The size may be a
bit of a problem, so please confirm the
diameter and
weight, if you can.
