Welcome mjhaman! I'm no expert but I know that Indian temple tokens show up fairly regularly in this Identification forum. That suggests that they are not terribly rare and were probably produced in large quantities, which means that they probably aren't worth very much. That suggests that they probably aren't frequently reproduced or counterfeited. Yours certainly looks authentic and I see no reason to doubt that it is. It's real value to the person who originally received it would have been spiritual rather than monetary. Unless you happen to be Hindu, I think what you have is a very interesting curiosity piece.
