ARINVS - a newly-discovered Augustus

[Arminius]

Looks like a Greek(?) engraver of the Cyzicus mint had some problems with the layout of Roman letters of the obverse legend:

Carinus, Cyzicus mint, officina 2, 283-285 AD.,
Æ Antoninianus (20-22 mm / 4,10 g),
Obv.: IMP N AVCARINVS P F AVG, radiate and draped bust of Carinus right, seen from behind.
Rev.: CLEMENTIA - •TEMP / XXI , Carinus standing right, receiving Victory on globe from Jupiter (or Carus) standing left, holding sceptre; B between.
RIC V, II, 178, 324 var. ; Coh. 20 var .

I´m no expert on these Æ Antoniniani. Are variants and misspellings like this frequent for Greek mints?

The error isn't quite that exotic IMP M AV CARINVS P F AVG ... with the R in AVR missing
