Hi,
Ian.
Caesarea Maritima.
COLONIA PRIMA
FLAVIA AVGUSTA CAESARENSI. The city was raised to the rank of
Roman Colony by
Vespasian (
Flavian Dynasty), and starting with
Domitian began minting coins in Latin, instead of Greek. Thus, "(of the) First
Flavia Colony
Caesarea Augusta". The inscriptions for
Caesarea were usually in the nominative case, indicating the city as the minting authority, but on some coins of
Trajan and
Hadrian, like yours, the
inscription is in the
genitive case, indicating possession. If you post a photo I can give you a more
complete reference from
Kadman's "Coins of
Caesarea Maritima".
Hope this helps!
edit: I just saw the one sold recently on this site that I think must be yours. Beautiful coin!
