I'm not in the market for a piano. Assuming your piano has not been rebuilt then it's only value would be as a rebuildable core. At 105 years old the sound board has experienced the shift from hot humid summer to dry winter and back enough times to reduce crown below usefulness. Any of the quality of original manufacture is long gone and what's left is the result of climate and use. Steinway pianos of the same vintage might get $5000. Your best bet for selling quickly is to offer the piano to a rebuilder. Good luck!
