There is no real suggestion that the controlmarks of the obverse and reverse dies are paired logically for the L. Calpurnius Piso series. So for instance the obverse shown above was paired in an earlier die state with the other BM Specimen illustrated below. And yet, that double axe and that knife look a great deal like this funerary relief created a couple of hundred years later on the other side of the Mediterranean.
