My First 5th Century BC Coin - Kyzikos Hemiobol

When I finally had a coin from every century since the 4th century BC (that's a total of 25 different centuries, including the ongoing one), I thought that my "coin from each century" quest would finally be over.
I did realize that there are 5th (and 6th, and 7th) century BC coins around, but surely I was not able to afford any of those? Right?

Then out comes this one, and I realize that if I don't take the opportunity I might never have another chance again.
The price felt right, if on the upper edge of my budget (1000 rubles, or about $17). The details were really nice (not as nice as some I've seen online, but better than I expected).

As expected for a hemiobol, this is a tiny little coin - only 9 mm in diameter, and about 0.37 grams in weight (my coin weighing system kind of sucks, but I was able to tell that it was somewhere between 0.32 and 0.40 grams, and 0.37 is what the catalog says).
Sadly, my coin photographing system also kind of sucks (smartphone camera), so I don't guarantee photo quality

There are a few specific subtypes, with different attributions, and I'm not confident enough to say which particular subtype my coin belongs to.
It does fairly certainly appear to be 5th century BC, however.



Kyzikos, Mysia. AR9 hemiobol, 5th century BC. 9 mm, circa 0.37 grams.
Obverse: Head of roaring lion left, 4 pointed star in upper left, all within shallow incuse square (maybe, hard to see on this example).
Reverse: Forepart of running boar left, tuna fish behind.

I'm not sure what the attribution is, though (too many similar varieties).
