Yeah, check the local ads to see what a cord of wood's going for. A cord is a stack of wood (and the wood has to be stacked) that's 128 cubic feet. For example, if you have 3 piles of wood that are 8 ft. long and 4 feet high and the pieces are cut to 16 in. length, so that the 3 piles are 4 ft. deep, you have a cord of wood. Find out what the normal length is in your area for stove wood. Its probably anywhere from 16-20 inches. Wood cut to stove length sells for more than wood that isn't. If the large diameter pieces are split, so that they'll easily fit in a small stove, the wood sells for more. Dry wood sells for more than green wood, because it should be dry before you burn it, as green wood creates much more cresote (which coats chimneys and can catch fire, causing a chimney fire) than dry wood and doesn't burn as well. Oak produces a lot of heat, so should sell for more than woods producing less heat, such as firs, pines, and spruces, and some of the other hard woods, such as white birch.
