How do I find the value of this? This used to be a gas furnace, but the guts are ripped out, so it’s just decorative unless someone restored it. New, these things cost well over $2,000. It’s cast iron and weighs a ton. I can’t figure out if it’s worth $10 or $1,000!

The value is created by the way in which you list it. "Cast iron stove, need this gone by tomorrow, $10 first come first served"
