We are pretty good here as a group at assessing the normal value of a trumpet, but how much value to you think a celebrity association adds to a horn value??
If a Martin is $3.5-5k normally... how much more is a Miles Davis one, or a Chet Baker?? How about a Dizzy owned King? A Maynard Connstellation? A Louis Armstrong 10-22?
How about a sideman association rather than front man? How about a Stan Mark black lacquered horn (now at the Sherman Jazz Museum), or a Don (or John too!) Thomas Callicchio 1S/2?
