Æ19 - Commodus ΚΥΖΙΚΗ (Ζ shaped as エ)

Cyzicus was among the most prolific civic minting authorities in Mysia during the Antonine and Severan periods, but the orthographic peculiarity noted here — the Ζ rendered in a form resembling the Japanese katakana エ — is a genuine epigraphic curiosity documented in provincial bronzes from this mint. Such letterform variants were not errors but reflect the idiosyncratic punch-cutting habits of individual engravers, and they occasionally serve as diagnostic markers for die-linking studies across the Cyzicene civic series.
