Thank you for your patience.
Based on the serial number you have given your piano was built in 1935. At 38 inches high it is a larger Spinet and is quite an early piano of this type, now being in the order of 80 years old.
Generally Pianos have a limited life span of around 60 years mainly due to the wear during use and natural deterioration of the mechanical parts over time, such as the action, the strings, the soundboard, the tuning pins, the pin block, etc. The life of these instruments can often be extended by careful regular maintenance/tuning/repairs and some restoration over the years or a total re-build/restoration of the major mechanical components. Thus one of the overriding factors in any appraisal valuation is the age and condition of the internal mechanics. Added to this is the fact that with this being a spinet it is quite a compact size and thus has a small soundboard which can restrict the volume and quality of sound produced. This size of piano is no longer made as it has been superseded by larger better sound producing uprights.
Therefore with the information I have and that which you have supplied, I believe your W.P. Haines & Co. Spinet Piano has a value in the $400 to $600 range for a private sale.

If you are disappointed in the value given ‘please do not shoot the messenger’, I can only give you a value based on the current markets and a reflection of similar sales. Owners of musical instruments often have a very sincerely ***** ***** that their ‘pride and joy’ is particularly valuable and sometimes it is, but musical instruments unfortunately generally depreciate with age. Many thanks and if you need any more help or explanations on the value I have given please contact me before you complete the rating.
