Strange coin sold only as "gold coin" with a
weight of 6,2 grams.
It exists a correspondent
antoninianus RIC 345 (or also called aurelianus) for Magna
Urbica, but the
weight of the gold coin is too high to be an
aureus.
A tentative of creating a binio or an heavy
aureus by making a gold copy of the
antoninianus? Or there can be any chance that it is a legit unpublished coin? There are for instance some
rare heavy
aureus for Magna Urbica's husband
Carinus, so it could have been maybe an existing
type also for her?
I attach also a photo of a correspondent
antoninianus RIC 345.
