Possible fake Tigranes II with reversed letters?

Hello all, I just acquired this coin on vcoins. I hadn't noticed the legend up close until I received it, and noticed reversed letters. Since I can also read and understand Greek, here are the discrepancies which make me believe that it is either a fake, or a mint error from ancient times.
The coin is of the Artaxiad dynasty, Tigranes II (95-56 BC), chalkous AE21, 9.07g, obverse is bust of Tigranes right, with Armenian five-pointed tiara, reverse is Tyche seated on a rock with a palm leaf and river god Orontes swimming below, legend (what should be) ΒΑΣΙΛΕΟΣ - ΒΑΣΙΛΕΩΝ ΤΙΓΡΑΝΟΥ.
1. ΒΑΣΙΛΕΟΣ on the right is written in reverse, that is from right to left, mirror image. The I is substituted with a Υ, and the Λ is substituted with the latin L, and the O is substituted with a Ω.
2. ΒΑΣΙΛΕΩΝ on the left: Ω is upside down, and the last letter N is a Σ
3. ΤΙΓΡΑΝΟΥ on the far left: is written in upside down (one has to turn the coin over) - except the Υ.
Since this forum is full of experts, has anyone come across anything like this, or should I return the coin?
Thanks

That's interesting. I know little about this area of collecting, but here's my speculation.

I don't think it's a modern fake; why would a modern forger do such a thing? Could be an ancient counterfeit, though, by someone with low Greek literacy.

 

That's what I think, too. A barbarous imitation, reasonably well done.
