Ancient Greece - Rhodes Drachm, question of authenticity

Hi!

I'm eyeing a very nice Ancient Greek drachma on an auction. The seller is legitimate, but he mostly have much later coins and only a handful from this era. I don't have much experience with ancient coins either.
Managed to pinpont the exact type : N#370901

At first glance, the coin looks good, but I wonder about some details of the surface condition. On the reverse, there is a suspicious mark, that may or may not be a toolmark.
Also on the obverse the surface is quite pitted. I'm not sure if this is just natural corrosion or it's some cast error (which would obvoiusly point to a fake).

Tracked down some other variations of the coin and some of them have similar, pitted surfaces:

Again, I don't have much experience with ancient coins. Am I just paranoid about the suspicious details that I've pointed out? Does this look authentic? I'd much appreciate some input.

It looks too perfect. But it seems authentic and genuine to me. But I'm not a real expert.

The place with the holes, the dimples - this is the place where the copper mixture was, which has corroded over a long time and disappeared. The green spot has fallen off or been removed.

So I consider the opposite of perfection to be authenticity.

I'm just a little uneasy about the nice circle of the coin. That's usually a symbol of new mintage. So I'll wait for other reviewers.
