Sorry no one got to you sooner, Iíll just send this direct:
Check on Ebay to see what you can get for your wood. I am always amazed by the things that show up there. Sorry I canít give you better information, other than to say that what makes wood valuable is if it is straight, knot free or ďclearĒ, and dimensionally stable and free of rot.
Be careful pulling it from the building not to mar it up too badly.
