Hopefully someone in the know will FReepmail you. Of course now that you've put the question out there, I'm compelled to find out!

Here is some info about Domitianus that I found on the net:

"Domitianus was proclaimed emperor at the beginning of Aurelian's reign, but killed soon afterwards. His rebellion seems to have been the result of the barbaric invasions at the beginning of Aurelian's reign. He perhaps is to be identified with the general Domitianus who is said to have defeated the Macriani about A.D. 261. The only coin minted in the name of Domitianus is probably a forgery."

It looks like historians questioned the genuineness of the coin found in France, but not necessarily the existence of Domitianus himself, as the article implies.
