Steinway & Sons model O 5’10” Grand
New today ≈ $80,000
This is one of the industries best made pianos. Steinway produced these models in the early 20th Century and changed the design for some visually aesthetic reasoning. Over the years they decided this was the better design for a 5’10” grand piano and started crafting them again in the early 21st Century.
It is in great condition currently but is certainly an instrument worth a full restoration. After restoration the sale price should be closer to $30,000+
