Mason & Hamlin BB Piano: What It's Worth in 2026, Prices & Listings
- Size
- 7' (213 cm) semi-concert grand
- Made
- Boston-built from the early twentieth century; made again in Haverhill, Massachusetts since the 1990s
The Mason & Hamlin BB is the seven-foot grand that made the company's reputation: a semi-concert piano with the tension resonator, a very heavy rim and a bass that technicians still use as the reference for the size. Recording studios, conservatories and serious amateurs with the room seek it out, and a rebuilt Boston-era BB is one of the few vintage American grands that commands new-piano money.
Like the Model A, the BB spans three eras. Boston-built examples (before the 1930s) and the modern Haverhill production are the ones with the reputation; the Rochester-built pianos of the Aeolian-American decades are valued well below them.

What to know about the Mason & Hamlin BB
- Identify the era from the serial number before you talk price: Boston, Rochester and Haverhill BBs are different pianos in the market's eyes.
- A BB weighs considerably more than most seven-foot grands. Confirm the floor, the doorway and the stairs before you buy a used one, and budget for a crew that moves concert grands.
- Rebuilt vintage BBs vary with the shop that did the work. Ask who rebuilt it, when, and whether the soundboard and pinblock were replaced or repaired.
- The tension resonator under the piano should be intact and adjusted; a technician who knows Mason & Hamlin can check it in minutes.
- Compare against a Steinway B (6'11"): similar size, usually a higher asking price for the Steinway, and a brighter voice. The BB is darker and heavier in the bass.

What is a Mason & Hamlin BB worth?
See the live snapshot above for what BBs are asking right now, then place yours by era and rebuild status: a Haverhill or well-rebuilt Boston-era BB sits at the top, a Rochester-era or unrestored vintage BB lower.
Mason & Hamlin BB or Steinway B?
They are the two classic American seven-footers. The Steinway usually asks more and is easier to resell; the BB is heavier-built with a bigger, darker bass, and many technicians prefer it. Play both if you can.
Will a BB fit in a house?
At seven feet it needs a large room and a solid floor. It is also unusually heavy for its length, so plan the move with a crew that handles concert grands.
