Can anyone ID this coin and it's mint for me. I believe that the ruler is Constans, but cannot find one that matches it on the internet. Most of the varieties that are similar have more lettering in the wreath on the reverse. The coin is approx. 18mm in diameter and bronze. Thanks!

20 year votive of Contantine I Ticinum RIC VII 167.3 Constantine I AE3 Follis. 322-325 AD. CONSTAN-TINVS AVG, laureate head right / D N CONSTANTINI MAX AVG, laurel wreath enclosing VOT (dot) XX and crescent below, PT in ex. (I think that is a PT, it might be QT)
