This ancient Greek coin is a mystery to me . It appears to be of silver composition and in a uncleaned state . It is uncertified, but its age and origin are unknown. This coin weighs 9 Grams or 0.3 oz. on my postal scale and it is 1 in. in diameter. I found this coin in a clean-out . I have no idea about its age and origin .  I also reached out to several websites and didn't hear back about this coin from any of them . This is not a scam , I have been selling on e-bay for over 21 years . Feel free to ask any questions . If you know the age and origins of this coin please share it with me . If its some kind of fake also let me know. I have no idea as to its value and that is why the high buy it now . Feel free to make a best offer . Thanks. Dan
