Large objects can be so hard to deal with that they are often discarded, regardless of theoretical price or value. Motorcycles, Hammond organs, etc.

So often it might be worth quite a bit it someone in another location, but especially after someone dies, there often isn’t the energy to deal with it. So on the street it goes.

You can find some people asking $6000 for a Hammond B3, but then someone can’t give away a D-152 outside of an urban area because folks don’t know what it is on a search. It better than a B3, essentially the deluxe model. But they weight nearly 500lbs and people don’t know how to turn them on to test even (it is a 2 step process)
