IOVI CONSERVATORI

Radiate, draped and cuirassed bust of Balbinus to the right, seen from three quarters ahead.

Jupiter standing on the left, holding a long scepter with the left hand as well as a victory with the right hand. The scepter is surmounted by an eagle turned to the left and holding a crown in its beak. The victory crowns Jupiter, holds a palm and is placed on a globe. On the ground to the left, an eagle holding a crown in its beak. On the right, a captive seated with his hands tied.

Photo of a coin sold the 01/12/2019 by Roma Numismatica Ars Classica, Auction 18, lot 1230, link to the sale: https://www.acsearch.info/search.html?id=6632074, link to their website: https://www.numismatik-naumann.at/. This coin shows the decoration (small balls) of the drape of Jupiter. Decoration often seen in the mints of Alexandria and Nicomedia.

The eagle surmounting the scepter is often very inconspicuous but always present on all the coins of the three mints known for Martinianus: Alexandria (new mint that I discovered), Cyzicus and Nicomedia.

There is a coin sold by Heritage Europe (formerly MPO Auctions), which according to the seller's description would have the SMKB mark, therefore Cyzicus mint. Link to the coin: https://www.acsearch.info/search.html?id=6875598. The obverse legend is clearly visible: D N MARTINIANVS P F AVG. This obverse legend is referenced for the Nicomedia mint but not for Cyzicus. Is this coin genuine? To check.
