@TIF First and foremost, those are both beautiful coins. Again I am tempted to leave my focus behind and just start adding more coins like yours here. Secondly, I would say I wandered into Nikopolis looking for coins of Septimius Severus as he/Julia Domna are my main focus or at least in the second century they are my main focus. I came across a coin or two at a show and once I started to figure out how to read the Greek and understand titles, consular legate names and what not I then started adding coins that were issued by SSev/JD. The other compelling factor is affordability. If you are buy bronze that isn’t an especially rare piece, prices are fairly low. Much lower than for comparable grade sestertii for example. Yet you can still get a 27mm Provincial which has plenty of room for detail and artistic expression. The Herakles and Serapis issues were sought out as was the river god issue.
