AR26 - Caracalla L - Κ

Caracalla's early Alexandrian tetradrachms from regnal year 20 (211–212 AD) were struck during the final joint reign with his brother Geta — a co-emperorship that ended when Caracalla had Geta murdered in their mother Julia Domna's arms in late 212. The Egyptian mint continued producing coins in both names through that year, meaning issues from this precise period straddle one of the more violent dynastic ruptures in Severan history.

The "L Κ" regnal date notation is the standard Alexandrian dating convention using the Greek letter lambda for "year." Egypt's mint operated on a distinct calendar year tied to the imperial accession count rather than the Roman consular year.
