Just for the record: Cannae was in 216 (August 2 or July 2, depending on how you interpret the calendar) as was Varro's consulship . The consul Aemilius Paullus was killed at Cannae, Varro survived and had other commands throughout the war. He remained in command for the remainder of the year, mostly based at Canusium. Crawford probably attributes it to a younger relative because Varro had no command in Sicily and issuing money was generally done by minor magistrates.
Great coin.
