Do accordions grow in value over time?
We've all heard the stories about someone finding an old violin in their attic that turns out to be a priceless Stradivarius.
This doesn't happen with accordions. An unused accordion that has gathered dust and mold for several years in someone's garage, basement or attic is probably just an old unused accordion that could be a piece of junk. It may have sentimental value to the family but has probably not grown in value over time.
Quality accordions, when relatively new, may appreciate slightly in value IF the price of their new counterparts has risen due to inflation. But over time and use, an accordion will need tuning and refurbishing. It will probably not have grown in value at all. Much like an automobile, it is going to deteriorate whether used or not. But unlike a classic car in mint condition after 50 or 60 years, the accordion is just going to be a really old instrument, not a classic.
Think about it. Famous violinists and 'cellists may perform on an instrument that was built by the Italian masters of the 17th century. Although accordion production does not go that far back in history, how many world-class accordionists perform on an early instrument, which means one crafted in the late 19th Century?
