Serial#22584 what year
I need a serial number to find the age of your piano. Shoninger is better-known for reed organs. If you can find the serial number--usually by the tuning pins above the strings, 25000 was 1901, 50000 was 1913, 60000 was 1918, to give you an idea. Value depends on condition and your market. It is probably worth at most hundreds of dollars if it is in good shape.
