Not as flashy as my recent acquisitions, but Maximus is one of those imperial figures who qualifies for a hole filler coin, and this will do nicely until a "BUY ME" denarius of his comes up. This was about $45 shipped.

Sadly, it appears that most of this fellow's life was lost to history. He was appointed as Caesar perhaps immediately after his father's nomination to the purple, and accompanied his father on his various military campaigns, first against the Goths, then against the allies of the Senate. He died alongside his father after the failed siege of Aquileia in 238. He appears to have been a teenager or in his mid-20s.
