I have access to a granite quarry in Montana last used in the early 1900s and would like to market the stone. It was all split by hand and still shows the drill and chisel marks. I dont have any idea what the going rate is for this kind of stone and wondered if you could help me find comparable products so I can establish a price. The only thing similar I have found is the reclaimed granite block taken from old foundations on the east coast. Thanks for your time.
