Amisos coin - strange obverse [opgelost]

This came as part of a lot. It's 20 mm and has roughly 7g (I need a more sensitive scale…).  The inscription on the reverse places it in Amisos. The reverse is similar to other Amisos coins (Nike walking right) - N#371256.

The obverse looks to be Nike walking left??? I could not find a similar coin in the Numista or Wildwinds databases.

Fake?

It appears to have been squashed together with another Amisos coin, leaving a reverse impression.

No way to tell when.   In the parlance of modern coins where this has occurred is call a “vice job.”

Thank you, Tmconst, for pointing me in the right direction. After some research, now I believe this to be a “reverse brockage”, but whether it's real (done at the time when the coin was struck) or later, it's hard to say. The obverse of this Nike reverse is a Gorgona shield. On this incluse obverse, there is no image of the “regular” obverse underneath the inverted, incluse Nike. If it's a modern “reverse”, somebody must've filed the Gorgona shield, but the coin did not lose a lot of weight - its weight is close to a similar coin from my collection (with correct obverse and reverse - 7.55g vs. 7.65g).

The unstruck flan, on the obverse, has the same pattern with this one: N#57337 so it might be real/ unfiled…

Thanks again!

Here are the obverse incluse (flipped) and the actual reverse. They should be identical, if it's a real “reverse brockage”. I played with them in Photoshop (made one transparent and tried to fit it over the other) and they seem quite similar (but I'm not Photoshop expert, so I might be wrong).

Interested in any opinion on this. Thanks.

Here is an example i own, which may give you more reason to doubt the quality control of the Amisos mint at the time.   It is a double struck reverse where one Nike is basically standing on the shoulders of the other.
