Value of coin ?

Are you sure that it’s authentic? Even with those blurry pictures the coin looks very crude and some details are off.

Please take some better pictures and tell us weight, thickness and diameter.

2.8 centimeters and i dont know its authentic how could i know is there anything that i know how is that coin is real thanks for respond 

Thanks for the new pictures, to me the coin does not look authentic. 

Multiple details are off and the surface looks similar to other forgeries of greek silver coins I’ve seen. 

For further help, where did you get this coin? 

Finding out whether this coin was bought at a flea market or a renowned coin dealer makes a pretty big difference.

Thank you so much
