Thanks.
If you ask me one of the greatest bust styles used by the Gallic emperors!
In AGK two examples listed.
- the one you published in: van Vleuten - Eine Münzsammlung aus römischer Zeit
Seeing the drawing it is not same one as you found on wildwinds.
- Vienna ex. Slg. St. Florian; this one is pictured in Mairat who has only one example listed
So now three known or does somebody know any others?
