Thank you for your patience Elizabeth.
From the maker’s serial number records your Piano was built in 1964, so it is in the order of 52 years old. The dimensions you have given are consistent with your piano being a model M which has a full length of 5' 7''. These new are now in the region of 90,000 CAD
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. The condition of the finish and location do have some influence on the value of a piano but the overriding factors in any appraisal valuation are the age and condition of the internal mechanics which depreciate with age and usage.
Outside casework can certainly help when selling as often pianos in reasonable to good condition more often than not sell by their perceived value.
Based on the information I have, I believe your Steinway Model M Baby Grand has a current value in the 29,000 CAD to 32,000 CAD range for a private sale. This range allows for some variations in location.

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 and use. 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.
