ANSWER:

Zakat must be given on paper money on the value of silver if you possess it for a whole lunar year! 

Can i give zakat on my paper money on the value of gold instead of silver.If no,& i must give on the value of silver then i dont knw whether 1 hijri year has already completed on my paper money on value of silver.One thing i can say is tht the money is already above the nisab of silver.If u say give zakat on paper money on nisab of gold then i dont hve tht amount yet.It will be easy for me then.
