Upright Player Pianos
This is for general advice only, and covers the spectrum of most pianos not all pianos. Value greatly depends on make, condition, cabinetry design, and player system.

This would also apply, in general, to digital systems such as Pianomation and Piano Disc. Pianocorder systems would be less.

Definitions:
The retail estimated value is if you sell to a private party for their own use.
The wholesale estimated value is what you might expect from a piano reseller/dealer.

The retail figures do not factor in extras such as delivery, tuning, and a guarantee that would most likely come from a piano dealer, not from you.

If your older player piano has been restored, you will need a more accurate appraisal. I would like a more accurate appraisal.
