Piano, Organ, and Keyboard/Steinway & Son's Piano


QUESTION: Hi,  My mother in law recently passed away and has a Steinway & Son's piano serial # 334482.  Trying to help my father in law out as we have no idea how old it is, what it might be worth etc.  It has been sitting for many years, although appears to be in good condition.  Any information would be helpful.  Thanks so much!

ANSWER: Hi Kellie:

The worth of Steinways are higher than most in whatever condition.

I would suggest strongly that you have it appraised first hand so that your insurance covers it properly.

You can go to http://www.ptg.org for a registered technician in your area. In the upper right hand corner there is a place to locate a technician.

Interview several. In this case I would want someone with no less than 10 years as a REGIESTERED piano technician with experience in appraisals. If you have trouble, get back to me.

The piano was manufactured in: 1951

The Model of the piano is under the removable music desk. Slide it forward and off. Stand in the middle of the keyboard. To your left in a triangle shaped cup there should be the letter designation along with the serial number. e.g. A, B, C, D, S, M, L, O

Keep me posted!

QUESTION: Thank you so much for the information.  So in looking we found on the left side imprinted in some gold looking metal behind the wires/strings the name steinway & son's and then looks like it says U3PT.OFF and then couldn't really find a triangle shaped cup but just to the left of the middle there is a metal piece that has C183 - also found in the right corner 3109 ? or another 3 E - and then underneath the keys is 17675 - a lot but just not sure what is what.  You are right on with the manufactured date - I found initials and a date:  2/20/51   

We will take your advice and get it appraised - but anything else you can tell me would be so great - thanks again.....I really appreciate your help!!

Hi again Kellie...


I thought this was a grand piano...nope.

Instead, it is a Steinway console. Thanks for the pictures!!!!

I would say the worth would top out at 1100.00 to 1500.00 in perfect condition.

Sorry about the confusion.
