Hi, thank you for your question! I have completed thousands of musical instrument appraisals and will be happy to help with yours.
Upright player pianos from this era are pretty neat instruments. This period was rich in player piano production as the new technology unfolded and as people were looking for new methods of entertainment. They were built in high numbers up until the great depression when this type of piano and piano building in general slowed dramatically.
In regard to value, it's important to know that pianos are valued not as antiques, but as mechanical instruments which decline in condition over time. For this reason, old upright players are valued much less than a comparable new piano. In addition, the high number of used pianos on the American market keeps prices low. That said, fully restored pianos can be worth much more than one in original shape.
Based on your description of the piano and its condition, and including the 150 rolls in the sale, I would recommend a private party value of approximately $500-$1,000. This assumes good playing condition and no major issues mechanically or cosmetically. Best wishes!Please take just a moment to select a positive rating for me before leaving.
