The secondhand market value of a twenty-year-old piano depends heavily on the original manufacturer, initial build quality, aesthetic condition, and internal mechanical wear. While a twenty-year-old high-end instrument from a prestigious maker like Steinway, Bösendorfer, or a well-preserved professional Kawai/Yamaha grand can retain a substantial portion of its value (often thousands of dollars), standard consumer upright pianos from lesser-known brands typically depreciate heavily, frequently selling for a fraction of their original retail price or given away for free.
