I've only had one Max Thrax, back in my old "A to Z" (Augustus to Zeno) portrait set (which was my first Roman coin pursuit in 2007-08). I like the stories of how he was a physical giant, and yet he often seems to have a rather mild and benevolent expression on his coins. (Cue the "gentle giant" cliche). He's kind of fierce-ish in some of the coins posted here, but he cracking a smile on others. I like that. Quite the prominent chin, of course. You can definitely tell this was a unique individual in this portraiture.
What are your sources for the exact date of Maximinus death? It was not preserved by ancient sources and Kienast considers mid April the most likely time for his demise... Anyway, a good reason to celebrate so here are my Sestertii of the Two Maximini:
I got it from some "today in history" website. Even if not the exact date that our boy Max cashed in his chips, it is a fun excuse to see a bunch of nice ancents.
