Hi! Thanks,Alexius73,for your message and kind help but… I already found for my own,on the net,the same link you gave me but(again) there is ''story'' of 2 (in general) big types of such coins: one,older,made of silver (the Sassanid drachma) and the other,newer,indian Gujarat imitations of the first one,made of billon. I couldn't determine what is mine and so,also,evaluate it.
Who can help for sure?!
