Telling us about the weight and diameter might make things easier, please do that. (and maybe toning down on the capital letters as the forum policy which you ignored says) 

Sir, weight is about 1.5g to 2g thickness is 2mm and diameter is 8.5 to 9 mm as listed sir, but i need a expert like you to confirm this coin is real Or fake sir

Looks like a ½ kasu from Mysore, India. Given the metrics.
Why do you think it´s fake?
 

Mysore has lot of fake coins so I need expertise concent about this sir
