However, the value of a used saxophone depends on a number of factors, including its age, condition, and provenance.
A used Conn 20M saxophone in good condition could be worth anywhere from $2,000 to $4,000. If the saxophone has been recently overhauled, its value could be even higher.
Some Conn 20M saxophones have special features that can increase their value. For example, a saxophone with gold plating or engraving may be worth more than a standard model. Saxophones that have been owned or played by famous musicians can also command a higher price.
To get an accurate estimate of the value of your Conn 20M saxophone, you should have it appraised by a qualified楽器 technician. An appraiser will take into account all of the factors that affect the value of the saxophone and give you a fair market value.
