Odds are good you would get ring burl (kinda like a birdseye) off the knobs and very possibly a fiddleback several inches into the tree if sliced properly at a mill. But...is money the motivator to cut it down? If its living and perfectly healthy then you must decide if greed matters more than the trees life. If it was my tree i wouldnt dare cut it until a storm took its life. The tree exudes a true beauty in its own gnarly self. People cutting up trees like this, or just randomly walking through the forest chopping off burls, they should be locked up imo. I am not a tree hugger either, i believe in using the earths resources, and replacing them...thats called responsible harvesting. Its removing 1-2 trees purely because they worth big money that i oppose...hope that makes sense.
