SELMER saxophones are indeed closely linked to great names in the history of music. Collectors often seek out specific series known for their special quality or their association with famous musicians. Saxophones made in certain periods or with specific characteristics can be considered rarer and therefore more valuable in the market. Each serial number is unique, so it provides information on the date of manufacture of the instrument and helps to establish its authenticity. The serial number is a key element to know your saxophone better.
