Hi everyone ive inherited a coin a while back from my late mother and it appears to be silver and weighs approximately 5 grams. the obverse shows a head wearing a corinthian style helmet facing right and the reverse has a incuse square with what appears to be a bird/eagle and other symbols. Ive been told it may be a greek coin but not sure whether it is genuine or a modern reproduction. Any opinions on identification authenticity and value would be greatly appreciated. Thank you
