Help for ID of Greek silver fraction [solved]

Recently acquired this small Greek silver fraction, likely a tetartemorion(?), but I'm puzzled about where/when it is from. It weighs 0.31g, and has dimensions of 1.0 cm x 0.7 cm. Obverse is a bust facing left with lettering on the right hand side, reverse is a raised design that I can't make out. 

Any ideas? Thanks!

Nice fractional!

Searched on our catalog, and didn't found yours here: https://en.numista.com/catalogue/index.php?e=grece_antique&r=left&st=all&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=&i=&b=&m=1&f=&t=5-10&t2=&w=0.1-0.5&mt=&u=&g=&p=1

I'll need to search elsewhere.

Searched at CGB, no luck there.

Hi, it looks like the head of Attis with a tunny fish under the head, present on the coins of Mysia Kyzikos, I will look tomorrow!

You mean N#376160 ?

Indeed this was the closest coin I've found during the search. But on his coin there's a Δ behind the head (and maybe a second letter). And then there's the almost unidentifiable figure at the reverse, but that's another matter.

Wish you luck on this one tatinos.

Hi, thanks Giobruno! I found this, I think it's good, Mysia Kyziko !

Head of Attis with the monogram on right!

If you turn the 2nd photo,  we can see the bull, so my link is good ! Mysia Kyzikos head of Attis with tunny fish with the monogram right, reverse the bull😉

You got me, I wouldn't think about rotating the 2nd photo. Not soon at least. Hat off to you.

And it looks that it's a rare variant, there's around 200 examples at acsearch (my search there) and only this one had a monogram visible (if I didn't overlooked any other).

Natprover, in your collection, the coin can be entered at N#376160 , which is the regular version of it, and the monogram presence can be written at the comments.

Thank you! I never would have guessed.

Hi, for information this coin sold for 35 Euros
