Stamp duty for charitable trust

Hi, We run a Charitalbe trust in Mumbai, which is registered under 80-G. Someone is willing to doante a Land / Flat / Property to our trust for our regular activities like Meditation camp, Medical Camps, Counselling etc.

My Question - Do we, as a Charitable Trust, have to pay the stamp duty on the Gift Deed / Donation deed executed. Since it may just say token value of Rs.1/- for the property. If yes, then at what rate?  Please guide.
