In J. G.
Milne, "The Autonomous Coinage of
Smyrna", NC 1923, 1927, and 1928, there is a list with all magistrates on coins from
Smyrna known to him.
There is no ΑΡΙΤΩΝ at all, and no KΡΙΤΩΝ (which also could be a possibility) neither.
Milne mentions ΑΡΙΣΤO (with omikron instead of omega) as the beginning of a name, but this does not occur on
Apollo and tripod coins.
So probably we have a new magistrate here.
