If you are considering getting an appraisal or selling your acoustic piano, you can advertise it privately online. You could upload ads or contact piano dealers or stores for advice. Before advertising or requesting an appraisal, assess if the piano is suitable for sale. Look at the brand, condition, and appearance. Famous brands generate more interest and value. Age alone does not indicate the actual condition. A buyer will be interested in the history of use and maintenance. A technician can provide an accurate appraisal by examining the mechanics, strings, tuning pins, and cabinet. Fully restored used pianos can be in exceptional condition. The exterior appearance is important. Scratches, chips, and cracks affect desirability and value. The serial number helps determine the age and country of production of the piano. Assess the internal condition, age, and maintenance to determine the value of your piano. The piano technician and tuner will perform an appraisal and provide judgments about the piano.

Brand
Famous brands with a good reputation will generate more interest and be valued more than lesser-known brands lacking recognition for quality. Some of the most sellable brands in the current market include Steinway & Sons, Yamaha, Fazioli, Bechstein, Kawai, Bösendorfer, Blüthner, Schimmel, Sauter, and many others.

Condition
The age of a piano alone tells us little about its actual condition, how much it has been used, or how well it has been maintained. A potential buyer will be interested in the history of the piano's use and maintenance. This is why a technician can help you understand it and provide an accurate and detailed appraisal by examining the condition of the mechanics, strings, tuning pins, and cabinet. Generally, used pianos that have been fully restored using only original and authentic materials and parts, due to low usage and favorable environmental conditions, can still be in exceptional condition.

Exterior Appearance
If your piano looks neglected, it is less likely to be sold. In addition to being a musical instrument, people also appreciate a piano as a piece of furniture, which means that many pianos that sound good may not be sellable if they don't also have a pleasing appearance. Therefore, scratches, chips, and cracks on the cabinet will negatively affect the desirability and value of a piano.

Determining the Age of Pianos
The serial number of the piano helps determine its age as well as the country where it was produced, which will be of interest to any potential buyer. The serial number can vary from piano to piano, consisting of numbers and letters or just numbers. This depends on the brand, model, and in some cases, the country where the piano was produced if the manufacturer has multiple factories, as is the case with Yamaha, Kawai, and Steinway. The serial number is usually printed on the cast iron plate or sometimes on the soundboard if it is a grand piano.

Assigning value to your piano should be the first step in selling your piano. The market value of a piano primarily depends on the condition of the internals, age, and how well it has been maintained. This is roughly what the piano technician does when performing an appraisal—verifying, checking, and then providing judgments on the examined piano.
