best call your insurance company first because if you got a 539' tall tree in your backyard then it's gonna leave ONE WHOPPER of a hole when you chop that sucker down
You'd have to get a certified arborist to look at that then the value if basically what it's worth to whoever chops the tree down...unless you hit it on the side of the highway then you best bend over and kiss your ass goodbye cuz the state is going to make you pay them $100million
