A trivia question that perhaps no one cares about is that Lysimachos actually renamed two cities in honor of his son Agathokles. There was Maroneia in Thrace, but also Adramyteion in Mysia.
The city could not have been named so for very long, since Agathokles was executed in 283 BCE, and the city likely renamed itself then.
These coins are relatively rare. Having two of one animal on a coin is called “Bicorporate”. In general, scholars today believe that a double-bodied owl (whose animal typically indicated Athena) was depicted more for a “cool” factor. Its use was typically decorative.
