Small silver Greek, punched

[sid]

I'm going to take another stab at clearing up a few mysteries I've had for a long time.
First up is this small Greek silver, 12 mm, 2.15 g.
The convex obverse has nothing identifiable.
The reverse seems to be of the very early punched type, maybe a square divided into four quarters, but with a rounded or Y shaped line at the end of some or all of the dividing lines. I'm not sure how well it shows up in the photo.
The closest I could find to the design on wildwinds is the obverse of this http://www.wildwinds.com/coins/greece/ionia/Svoronos_8cf.1.th.jpg. But that's not the punched side, and the other side doesn't match at all.

I think I've found a possible match, a Parion, Mysia hemidrachm

In the wildwind examples, there doesn't seem to be a consistent weight range for the drachm, 3/4 drachm and hemidrachm, and mine is just a tad lighter than the lightest coin in the bunch. Can anyone confirm my ID and whether the weight is right?

     Ave Sid,
 
   I don’t know regarding your ID, but, just for the mention in case you’d missed it – there’s one that may be of the same type per your speculation at CoinArchives, that reportedly weighed in at just 2.11 grm.

   Most there seem to be 3.+ grm …

  Best,
