Roman empire coin

                                  I need some.opinions to identify this coin. 

Silver , 18mm, 3.27g.

În my opinion is RIC III 468..?

Thanks in advance!

By searching in the catalogue for CAES ANTON, which is part of the obverse legend, you get coins from the right period.

However, the odd style of the lettering in the legends, especially on the reverse, suggests to me that this could be a so-called “barbarian" imitation — i.e. a contemporary forgery that did circulate on the fringes of the Roman Empire and beyond.

This is just a hypothesis. Perhaps someone else can confirm or say otherwise…

EDIT — I missed the fact that you suggested RIC III 468. I believe you're right, unless it's an imitation of that type.
