That's it!!
The Apollo side at the reddit photo is compatible with the Apollos on the specimens at CGB, and look that they have 10 of this type available, so we have a reasonable sample size. But all 10 have Athena facing left.
If a right-facing Athena is really that rare, congrats for getting a really uncommon coin.
The one I own have a griffin head at the obverse. The photo on Numista shows it facing left, but both orientations are common (and CGB have more right-facing ones available than left-facing ones).
I've looked at the Lampsakos page here and (of course) we don't have this coin at our catalog.

One last thing, since we browsed the Ancient Coins reddit (I look there sometimes): as they say when someone acquires or showcases one of these, welcome to the fractional club.
