There are a ton of traits that will define the value of any accordion, but one way is to look around at what others sold for. Liberty Bellows sold a few in the $2500US range and those are usually in great shape as they spend time prepping them before selling.
Now, NO OFFENCE to anyone, but “plays great” is no guarantee that inside everything is in perfect condition. I recently had an accordion sent in to a professional for a couple valves and some minor spot tuning… and low and behold, it was 140 valves, a pair of bellows gaskets and touching up of 20 on the right hand, 5 notes on the left, and a rewaxing on 2 of the 5 pallets, so a pro may have a different opinion of the true condition of any given accordion, and I thought she sounded great too.
Hi Jerry- I am most interested in learning the accuracy of the date in which this was biult. The serial # is 171 and the luggage case is very unique (I have not seen this kind of case before.) I am wondering if this is a New York Excelsior from the 60s or 70s.The case includes a felt cleaning pad with the inscription Excelsior New York. Who should I contact to get this information?
