Hemiobol

Have a nice weekend colleagues.

The material is silver, the weight is 0.21g and the size is 6.6mm

I don't have a catalog to verify my theory that it is Hemiobol SNG KAYHAN 971 (972)

And I also made a note,, HNonline 969) and I don't know what it is.

I think it's two bulls with horns fighting, It should be Ancient Greece-,,Caria,, -500 to -450 B.C,  Hemobolus

Sample size

I have big doubts - The weight of similar coins is 0.49g.  and mine is half lighter for the same size?

Does anyone have experience with this - or access to the literature?

 N#186062-By weight and size, it could be this one, only the back doesn't match it?

These are the examples I'm comparing my coin to - the only problem is that mine is half the weight:
