This coin was unique when the RIC volume II revised edition was published in 2007. The authors of RIC presumed it was a mule using an obverse of Vespasian and a reverse of Domitian. From 2007 two more specimens (including this one) have appeared on the market, all from different die couples from the one published in RIC. This element is a strong indication that this issue is most probably not a mule.
