The following discussion provides information on how you may be able to establish the approximate value of your musical instrument. A more definitive estimate can only be made with a professional appraisal.
There is no simple guide to determine a chemnitzer concertina’s value. A mass produced 76-key instrument made in the early 1900s that has double reeds (two reeds sound for each button pressed) may have much less value then a modern, custom manufactured 104-key chemnitzer that has specially tuned quadruple reeds, high fidelity internal microphone and switches for multiple voices. Collectors or nostalgic musicians may be interested in the older concertina, while professional or serious hobbyist musicians would most certainly be interested in the modern concertina which greatly increases its sales price.
The brand, or manufacturer of your concertina will also have a bearing on its value. Some manufacturers utilized better materials, design, construction processes and tuning methods. These efforts produced an easier playing and better sounding instrument that remains in greater demand by knowledgeable chemnitzer musicians.
Determining the value of a chemnitzer concertina can be difficult. So many variables can affect the instrument’s eventual sales price. An assessment must be made of the instrument’s playing condition; do all buttons operate, do all reeds operate, are there no air leaks (you can suspend the ‘box from one handle with little or no leaks), is the finish good (no chips, cracks or missing pieces), is the bellows leather good, is there a musty or mildew odor, are all reeds in good tune, etc. Depending upon these factors, it may possibly be worth thousands of dollars. If it has any defects or problems, usually only detectable by an experienced chemnitzer musician or technician, it could be worthless.
Vintage instruments are more difficult to value. They are often cherished more for their nostalgic interest rather than their musical quality. The early concertinas generally do not have the sound quality or mechanical performance that make the instrument more desirable to today’s professional musicians and serious hobbyists, although some specific early models are known to be exceptional performers.
Understand that it’s very difficult to appraise this type of musical instrument without having the opportunity to see it, hear it, touch it, even “smell” it. Vintage free-reed, bellows-driven instruments such as a concertina, bandoneon and accordion are very organic, being made using materials such as wood, leather and paperboard. As such, they are susceptible to extreme environmental conditions; too much moisture, too little moisture, too much heat or too much cold. If the instrument was stored in a basement, attic, garage or enclosed porch, or if it has not been used for many years, it may have already suffered damage. Even if the concertina appears to be perfect on the outside, there could be serious issues with the components on the inside. Keep in mind that repairing these instruments can be a very costly proposition.

Vintage sheet music typically has no special value. There are some collectors who look for decorative copies to frame and display. You may be able to sell original printed sheets. Their value will depend upon the song title, cover design, and condition. Photocopied or handwritten arrangements typically have little to no resale value.
