It's surely
Septimius Severus, and
still in the 190s, such as the governorship of Barbarus in
Thrace. See if you can make out any letter sequences on the
reverse. I only checked the big Barbarus
obv. of Septimius (with a similar
eagle), but it isn't that one. But there are Barbarus signatures all over
Thrace, so it occurred to me to check there first. If you look at the attached, you'll see that it's not the one, but the same character of image, and a big coin.
