I can just tell you what
Ziegler says: While when the coin was minted, Anazarbus held only one
neokoros title (as also indicated by the coin's
legend NEWKOWN, not B NEWKORWN), but wanted to make a statement that it
had all the prerequisites for a second one (thus showing the two templed represention two
neokoroi titles) in order to keep up with Tarsus, its rival city. The latter already
had a double
neokoroi title, at the time, and
Severus seems to have shown quite some grace to Anazarbus which obviously
had supported him in the civil war of 193.
However, indeed only two years later (204/205 AD), Anazarbus received its second
neokoros title (the first city receiveing two
neokoros titles by one emperor).
Seems like a
good theory to me.
