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.
Used pianos have little resale value. I had an experience very similar to your, beautiful carved oak upright. I literally couldn’t give it away when we were moving. I was going to break it up but finally the buyer agreed to accept it for free

Repurpose it.
