Goebl shows lots of these hybrids of
DIVO CLAVDIO with many different reverses. So many that it seems to me that it's not accidental as you would think, like in the case of a
mule (what a fantastic descriptive term. What else would you get when you combine a
horse and a donkey?). Also the same reverses overlapping with
IMP CLAVDIVS obverses and
Quintillus as well. It seems somewhat haphazard, so perhaps it's related to the troubles
Aurelian had with the
Rome mint? I only recently purchased Goebl, and I have been lazy with my
German and haven't read it yet, so I don't know how or if he explains this.
