My MASON and HAMLIN bears the serial AA 13509.what year was it built. Under the top says Boston.
@ Beulah Grace Palmer, It looks like it was in late 1902. 1902 12800 – 13599. This may not have shipped until 1903 as it was very late in the 1902 production run.
I bought a Mason and Hamlin. I was told it is a 2018, but my husband found the year I scripted under the pian that says 2016.
The serial number says 93857.
So how do we really find out the year. I can’t find any website that shows me a serial number past 2013.
@Marie, I have also tried to find this information and can not find a age list either. I would say send the question to them directly and they should be able to answer this for you. Note in many cases the parts are made at different times and that many be the marking for that part of the piano. This happens with many different items. I have included a link to the contact form for Mason and Hamlin for you.

I recently purchased a Mason and Hamlin A6 grand. It has no serial number. It says patent pending 1917. Could someone tell me the year it was made?
My father purchased a refurbished Mason and Hamlin grand back in the ’70s. I found on the soundboard where it states BB1 at the very back of the piano, but the serial number is not there. I couldn’t find anything resembling a serial number on the soundboard. The only thing I found were some numbers stamped in the wood underneath the keyboard. The format looks wrong for a serial number though. It looks like this
238
398 81
I could presume the bottom number to be the serial number, but the space between the 2nd and 3rd digit makes me unsure. Any ideas? I’m trying to determine its value and possibly find a buyer in the Dallas, TX area.
