Stamp papers verification

I need a procedure that how to verify these Stamp papers in Hyderabad or In Nasik. For submitting the verification documents in the Civil Court for the final trail my Property case. I have Three photocopy of the Stamp Papers Non-Judicial from Hyderabad Sir, my understanding is that, the logo of the Non-judicial Stamp Paper with the slogan 'Satyamev Jayate' below symbol of Ashok Chakra is started from 25.02.1977 but on the stamp paper date mention is 20.4.1974. So clearly, it’s a fake. In another Stamp papers is department is not providing any information and not available. I already applied through R.T.I request in Stamps and Registration -Hyderabad T.S. But they gave me replied that, we don’t have information for this.
