Offers for Grady County - Selling Mineral Rights

Any information available on current status for S17 T7N R5W? Right, this is for SALE, not lease bonus. Need information to help a family member assess decision to sell. This is for 5 NMA, leased to Continental.

I wonder what I could get for 22.5 acres in 10-5-7, which are currently leased to Unit ?
