Hello and welcome to the forum. It appears that your piece might be from India. Is it silver? Some of the other experts I am sure will chime in soon. This is another forum that you can try. A lot of experts on all coins there. Try it. Olmanjon http://forums.collectors.com/
It does look from India maybe Kid Romeo who is a member of CT can help. He is usually pretty good at figuring these out.
It looks very similar to coins thatI have seen from the Delhi Sultanate (1193-1526) so that might well be a starting point for you, have a look at the coins from the earlier period.
