Recent purchase of silver diobol circa 500 BC

[cobra_fat]

I bought a coin with the following info attributed to it:

 

This is a very early, and scarce, SILVER issue of Asia minor. From Ancient Greece comes this silver diobol (two obols) from the city of Phokaia in Ionia from around 500 BC. Smaller than dime-size and fully attributed.

obv: crude head of a horse facing left

rev: incused stellated square

 

I can find no coin that looks like mine and I have been looking everywhere. No horses at all, just griffins, athena etc. Sorry, no photo yet. Has anyone heard of this type?

Are you sure it is the head of a horse, and not a lion?

Does it look like this?
