Antoninianus of the usurper Proculus, executed by Probus, AD 281.

The coin is only the second known antoninianus of Proculus, the first having been sold by auction in 1994 (Munzen und Medaillen Auction 8, October 1994, lot 640). The present coin is from the same obverse and reverse dies as the auctioned coin, but the reverse is better centred, with the entire legend on the flan. Both coins would appear to have a higher silver content than the official and contemporaneous issues of Probus.


The authors of RIC V, Part II (1933) wrote:

"During the reign of Probus, in about the year 280, two generals, PROCVLVS and BONOSVS, who had allowed the Germans to achieve some success on the Rhine, and feared the anger of the emperor, assumed the purple in Gaul, the former at Lugdunum and the latter at Cologne. It is said that the latter was of British descent, and was as great a devotee of Bacchus as his colleague was of Venus. Probus at once attacked and, after a severe struggle, destroyed first one and then the other of them.

Of Proculus no genuine coin is known, but a few pieces bearing the name of Bonosus deserve consideration. Like so much of the local coinage of Gaul, they are blundered."
