PLEASE NOTE: I will not be able to answer any questions about antique keyboards, accordions, concertinas, woodwinds, brass and percussion.

I can answer most questions on fretted instruments, my main area of expertise is in vintage mandolins, guitars and ukuleles. I also know some things about old banjos as well.

I have decided to no longer evaluate instruments -- it is very difficult without the instrument in hand. For guitars and some other American fretted instruments, I recommend the Vintage Guitar Price guide. Also, be aware that most insurance companies want written appraisals so my valuation would not work anyway.

ALSO PLEASE NOTE: it is near-impossible to accurately appraise a violin or bow remotely. If you truly want to find out what you have, you will likely need to take it to a reputable local dealer. Many of these folks will at least give you a verbal assessment of what you have after an inspection in hand and, if it is indeed worth something, can write you up a formal appraisal, usually for a fee.
