hi, I want to know if my identification is correct.
For me this coin is a specimen of CARUSIUS, I think it is a FIDES, but I would like to know what number of RIC could be. is it possible?
Thanks!

•FIDEM MILIT Ric 32 (London mint).
•FIDES MILITVM Ric 33
•FIDES MIL, MILIT o MILITVM from Ric 224 to 228 (Camulodunum mint)
•FIDES MILITVM Ric 608 (RSR mint)
•FID AVG, FIDEM AVG, FIDE, FIDEM, FIDES MIL, MILIT, MILIVM, MILITVM Ric from 780 to 783 (unknown mint)

PS I apologize for my English, but I'm Italian and I'm using Google translator!
PS2 the specimen is not mine, it's a photo downloaded from internet that I am using for my study about CARAUSIUS so I can not give different pictures!

...ça me semble une imitation de Carausius au type Fides...quant à connaitre le type exact c'est trop demander vu l'état de la monnaie...

you really looks like a local issue? I thought it was an official release, the style did not seem "barbaric".
I read these legends: obv. "I [...] SI [...]" and rev. "[...] DES [...] IT [...]" so a possible legend may be: IMP CARAVSIVS P F AVG for the obv. and FIDES MILITVM for the rev.
I think it's very interesting the idea of ​​a local imitation, but what do you suggest this?
I also know this information: AE; 2,05 gr; 19 mm; or. axis 3h.

...le style est vraiment grossier... et le poids ne plaide pas non plus en faveur d'une frappe normale... mais je ne suis pas un specialiste du monnayage de Carausius....

In this very bad grade, impossible to be precise. Because of it, I think it's not possible to use this coin for a study...
