inhertance farm sold

I was one of six of my family that inheritance of our family farm ,we had it appraised right away in 2008,  the farm property was sold 4/2019 . don't understand if I can use  2008 price as purchased price or not? have a lot of expense in selling and lawyer bills due to a court case over it? I understand I only claim 1/6th of everything. any advice is helpful thanks
