Half Rupee 1911

I would like your valuable suggestions regarding Originality, grade and price.



Thanks for looking  

Do you see a little dot at the bottom of the first picture?
Than it is minted in Bombay.
Calcutta mints have no mintmark.
The Calcutta mint is rather valuable and is reproduced as fakes.
The condition is rather worn
This site gives a high value, while Krause tells that the value is very low for this coin.

So I do not know which information is correct
