QUESTION: My mother has a Mathushek & Sons upright piano her parents bought her in 1947. She had it restored in the 1970s and discovered it was made of persimmon wood. The serial number is 27990. I've attached pictures. You can see pictures of the actual piano at https://www.estatesales.net/GA/Chickamauga/30707/1226334. Can you tell me it's value l?Thanks.

ANSWER: Amelia:

The piano was made in 1894.

Completely restored means the following

New Sound board
New Bridges
New Hammer butts and flanges
New Damper system
New Hammer shanks
New Hammers
New Pin Block

Is that what was done?

QUESTION: Yes. Everything.

Then the piano has to be worth around 10K.

A rebuilding like that in the 70's would have coast around 15K - 18K.

Is that what was invested?

You will need this evaluated first hand.

go to ptg.org and go to where is says: Locate a Technician.

You can use your zip code to locate a registered tech.

With that kind of money invested, you will want to make sure to have something in writing verifying all the work that was done and the present status of the instrument.
