When my mother sold her home I contacted anyone and everyone to try and donate a piano. Nobody wanted it. I couldn’t even giveaway the ivory key veneers.
Once upon a time I wandered through a real estate open house (estate sale I believe) in my old neighborhood. The home was probably mid-1950s and was brick and built into the natural slope, so there was a french doors walkout into the back. At some point the homeowner had constructed some retaining walls which made the back yard more private. Turned out, the piano that was in the finished basement had come in that way, and wouldn't go through the stairs, doors, and turns of the house, so the piano was part of the deal, unless someone had a bright idea and would move the piano themselves for some low low purchase price.
We’ve got an old upright, circa 1903, that we got “free” from the wife’s grandmother. Had it refinished for $700. It plays well but just sits there now...never used anymore. Will probably have to take the chainsaw to it to get rid of it. Not a bad piece of furniture though, lol.
Another item that’s hard to get rid of...entertainment centers. Ask me how I know.
My joke about organ donation is: Okay, I’ll take a Hammond B3.
When my in-laws moved we tried the same thing - no takers.
And it was too expensive to hire movers just to take it to the junk yard. I spent an afternoon down in the basement with a saw, sledge and crowbar tearing it down into pieces we could carry upstairs and out to my truck.
