It's been almost a year since this was posted, and still no replies, so I'll take a shot at it. By the way, I don't think the images are "lousy" but rather entirely adequate for the purposes of identification.
Size & weight below what you'd expect for a genuine coin of the period, plus the legends look pretty much like gibberish to me. Therefore I'd judge this to be barbarous. Such counterfeit antoniniani were often modeled on issues of the Gallic Emperors. so if any resemblance of the effigy to Tetricus wouldn't be remarkable.
