IOVI CONSERVATORI - A new reverse type for Victorinus?
A short summary of the following article (which also includes a die-study for IOVI CONSERVATORI reverses of Postumus):
"S. Sondermann, IOVI CONSERVATORI - Ein neuer Rückseitentyp für Victorinus?, Numismatisches NachrichtenBlatt 1/2009."
A new Antoninianus of Victorinus with IOVI CONSERVATORI reverse turned up recently. The reverse type is not known for Victorinus, the style seems to be official:

The reverse type is well known for Postumus Antoniniani. Indeed, the reverse is die linked to a IOVI CONSERVATORI Antoninianus of Postumus (British Museum, Duke of Devonshire 1844). Additionally regarding the worn dies, it concerns most likely to be a "mint-forgery"1, struck under improper using of an old Postumus reverse-die in combination with a mint II obverse-die of Victorinus by the mint employees.
A similar specimen is listed in De Witte:

A Fragment of a Postumus-Aureus
A short summary of the following article:
"S. Sondermann, Ein Fragment eines Postumus-Aureus, Geldgeschichtliche Nachrichten 238, Mai 2008."
In the year 2006 a detectorist discovered a fragment of a Postumus Aureus near Gloucester. This specimen seems to be the first known gold coin of the Gallic Empire, deliberately cut in ancient times, and is the third gold coin of Postumus, ever found in the United Kingdom (thanks to R. J. Bourne for this information).
