This coins was originally sold in a small and
provincial French auction, with other
ancient coins, maybe 5 months ago. Sold for something like 700 or 800€. Then I have found it in the
auction of a Belgian dealer.
I am quite sure that I have already seen another very similar
sestertius. With the same kind of Antoninus and
Faustina busts, with 2 busts, one of each
side. This
sestertius was in the "hell" of the Cabinet
des Medailles, in
Paris, with many other ancient
fakes. It was well done, exactly like yours, and hard to detect with only a picture. But the edge was not
good, like yours...
Be careful, because it's also exist with
Hadrian and
Sabina.
