Offers to purchase 9-7-6 Grady County

Just got another offer to buy my mineral rights in 9-7-6. Not selling. But for general interest here are details:

85 NMA, $21,000 per NMA at 3/16 royalty, total $1,785,000. Offer from The Mineral Resources Company. Offer by mail enclosed a contract and a deed. Not selling… at my advanced age it would just create estate problems, income tax problems, etc., etc. (If I were inclined to sell I would never handle this much money without a formal closing with exchange of $ for deed).

Some of these offers that I am getting lately make me wonder just how serious the offeror might be, or whether it is to get the commitment from me in order to flip to a serious buyer.

Anyone know who this outfit is? Based in Oklahoma City.

The Mineral Resources Company is part of Continental. I got a call from a landsman working for them as an independent agent, offering 20K/net mineral acre. I counter-offered and he got management approval for $25K. This is for a parcel in Grady Section 21.
