Æ20 - Caligula ΜΙΛΗΣΙΩΝ

Miletus retained the right to strike bronze coinage under the early Principate largely because Rome had little interest in controlling small-denomination local issues — civic bronzes like this one filled a practical gap that the imperial mint at Rome never bothered with. Caligula's brief reign of less than four years means the window for Milesian issues bearing his titles is narrow, and the city's output during this period was modest.

The reference I#2707A suggests a relatively obscure die pairing within the series.
