Will,
Most people here say never sell any ever, you proved them wrong big time as mineralhub has 205 net mineral acres listed for $350 per and if you sold back when you were offered $4400 per acre lease bonus you would have made a bundle, probably $10,000 to $15,000 per acre loss. They are hard to sell even at $350, those listed are in the SE corner though. Yours would fare better since they are in the western part of the County. Oil prices are high right now especially considering the world economy, I wonder what they’ll be saying if the bottom falls out of oil.
