Sterling Piano

We're not sure if this is the correct "Sterling piano company" but it's all we can find. We've already requested the piano be dated by the historical society and await an answer. http://derbyhistorical.org/sterling_piano_company.htm

This piano came with our home, with is a Bethlehem, PA row home, built in 1923. We're not sure if the piano has been here since the original owners. We know that the last owners (1 year only) and the previous owners (20+ years) have had it their full ownership period.

The piano as you can see in the pictures, says "Sterling New York" and under the lid the Serial # reads 80052.The company above (the website states) only made pianos from 1860s - 1920's. Was there any OTHER Sterling piano company?

We want to know these 3 things: How much is it worth as it stands? How much would it cost to refurb the entire thing? AND most importantly, how much would it be worth after refurb? We've seen someone state they were told they could get $22,000 for their VERY similar, same brand piano.

*NOT SURE* If the bench came with the piano or not.

So, we're trying to decide: junk yard, sell as-is, or refurb and sell? It's taking up precious dining room space!!
