Help with Purchase Offer

I own 1/14 mineral interest in 320 acres in Lea County, NM, Township 16S Range 37E, the SW 1/4 of Section 10 and SE 1/4 of Section 22. I have received an offer of $10,000 total for the mineral rights. Is this a fair offer?? I’d like to sell, but it is not an emergency to do so now. Any help would be appreciated!!
