1. Brand and Model: Clarinets made by reputable brands such as Buffet Crampon, Selmer, and Leblanc tend to have higher value. Each brand and model may have distinct features and sound characteristics that make them more desirable to players and collectors.
2. Condition: The overall condition of the clarinet is crucial. Instruments that are in good playing condition, with no cracks, major damage, or excessive wear, will hold more value. The presence of original keywork, mechanisms, and finish enhances the clarinet's worth.
3. Keywork and Plating: Clarinets with silver-plated keywork are generally more valuable than those with nickel-plated keys. Intricate keywork designs and engravings can also increase the instrument's appeal.
4. Originality: Original parts and accessories contribute to the authenticity and collectibility of a vintage clarinet. A clarinet with its original case, mouthpiece, ligature, and other period-appropriate items might fetch a higher price.
5. History and Provenance: If the clarinet has a known provenance, such as being owned or played by a famous musician or having historical significance, it can significantly increase its value. Documentation, receipts, or certificates of authenticity add value to the instrument.
Given these factors, it's difficult to provide a precise value without examining the specific clarinet. Consulting with reputable musical instrument dealers or knowledgeable collectors who specialize in vintage woodwind instruments can help you determine a fair market value for a 1959 wooden clarinet.
